Rotterdam metro time measurements and giants at the end of the lines

A while ago I was inspired to measure (with a stopwatch on the go) the time it takes for the Rotterdam metro to travel between each and every station , in order to find out which two metro stations are the furthest apart. Before I went through with that plan, however, someone reminded me that I was (literally) inspired by the methodology of a psychopathic metro slasher. The general Rotterdam metro schedule is actually available for download on RET.nl (in pdf form too). You can get them for lines ABC, line D and line E, listing the times the metro arrives at key stations in the system. These pdfs also include specific scheduling differences during weekends and holidays. Apart from these standard schedules for reference, the live metro schedule is updated every day on the RET site, informing the public on any newly announced changes. The act of getting on the metro and then personally measuring and composing this schedule for yourself is redundant on every practical level.

On a poetic level, however, a worthwhile produce of this personal measurement would be the very experience itself. Measuring metro times can be an exercise that helps you to REALLY take the metro, an exercise that helps to train your attention on the carrying public-transport mechanism itself instead of on other things in the environment and other things on your mind. Watching numbers go up on a stopwatch has a specific effect on how you experience and understand the passing of time. (I wanted to say it's really fast and really slow at the same time, but that's just gibberish though) The metro ride between the stations Portugaal and Tussenwater takes 1 minute and 34 seconds, for example, but WHAT DOES THAT NUMBER MEAN? Try measuring it once for yourself and maybe you'll figure it out. Anyways even if this psycho-poetics is not up your alley, there is no harm in measurement as confirmation. If you really can't spare the effort to perform measurements while travelling on the actual metro, you can also do it while watching these recorded videos of the Rotterdam metros' entire routes.

As for me, my purpose was never in knowing the exact time it takes for the metro to travel between every single station, but rather to FIND the two stations that takes the longest time in between, and therefore the two that are furthest apart from each other. Instead of spending hours with a stopwatch on the carriages, I have approached this in two ways. First, I've checked the schedule on RET.nl to find the two stations that has the longest time in between: Slinge and Rhoon on Line D. On this schedule the distance takes 5 or 6 minutes to travel, that's more time than between any other two stations in the system. Secondly, I have looked at the Rotterdam metro routes on Google Maps, and through some measurements using the Google MyMaps tools I've determined that truly there are no distance between any two stations greater than the distance between Slinge and Rhoon: 5.25 km (approx).

Only then, as confirmation, did I get on the Metro Line D to travel through those two stations and stopwatch-time it for myself. I did some test measurements in the stations before. The standard is to measure from the moment the metro doors close to the moment they open again at the next station. The final result of the measurement between Slinge and Rhoon was 4 minutes and 43 seconds. This is the longest time it would take to ride between any two metro stations in the Rotterdam metro system. If you wish to perform any activities while travelling on the metro between these two stations, this is approximately the time you can work with in your agenda. Another interesting thing to do during this time may be to listen to a song that's exactly that length. Or maybe play a game of charades? It's 4 minutes and 43 seconds of non-stop travelling in a closed metal box. It's whatever you make of it.

I've never been to the end of Line D (station De Akkers), so when I went out to take the measurement I thought I'd also go on to see what's there. And then at the very end of the metro line I saw two white whales. I definitely wasn't expecting them.

De Akkers

From Google Earth

After some internet research I found out that the sculpture was created by Rotterdam architect Marteen Struijs in 2002, so at least I know where they came from. But the key question remains: what are these things? Power animals? Guardian spirits? Alien intruders? To complete the narrative, I went to the other end of the metro, the far end of Line B at Nesselande, to look for clues.

Nesselande

No whale heads here, but the end of this side of the metros is again situated in water, and maybe that is continuity enough. I think the whales are not guardians or mascots. The whales ARE our metros. Our city is their ocean, and we travel in the bellies of the beasts, under and above grounds, to the day's various destinations. It is at times like these that I wish I've read Moby Dick.

Regardless of whether you've read MD or not, once you have given the metros the characters of living things, travelling with them become that much more fuzzy. It's difficult to lay your emotions on cold metal moving boxes, but it's easier to lay them on warm-bodied mammalian giants if they are willing to share your concerns. There were times where I left some places to catch a metro, but only on the metro did I realize I probably should have stayed. But blaming yourself is the worst. You can blame the White Whales instead. They will let out that all-majestic deep hum, and carry your stupid shit to the end of the lines.

bells and chimes thoughts

World Trade Centre at Beurs

Lately I caught a cold. I cough at night and don't sleep too well. The one good thing that came with it however was the strange dreams I've been having. Last night I was in a alternate dimension where the only life-forms are sentient buildings. These were houses and high-rise apartments that were conscious and could communicate with each other. They communicate through ringing metal bells. They sound like church bells. Every building also has a main bell that is hung in front of the entrance, it's the biggest bell and it's shaped like a silver nose. These buildings (mostly yellow in colour) are really chatty and the bells never stop ringing in the village. Ringing bells 24/7. The buildings don't ever sleep because they are buildings. It's a continuous long conversation.

I woke up in a cold sweat at 3 am. It wasn't scary, the imagery was just too cool. This other time last year I was walking outside in Rotterdam on a windy winter night and I thought of an act of terrorism where we could hang wind-chimes up on trees and lamp-posts before the winds come. The metallic chirps that never go away is going to drive all pedestrians insane. Wind-chime city 24/7, this is Batman villain stuff. Regular villains rob banks, but super-villains are fond of messing with your head with urban theatrics that are elaborate and symbolic. Last week I've read the Amazing Spider-Man event-arc Spider Island, where every person in the entire island of Manhattan was turned into a giant spider, and Spidey had to save everyone. That kind of scheme really only makes sense in cities. Take any super-villain mastermind out of cities and (s)he is a fish out of water.

Disregarding the villainy, wind-chimes can be my friends, I like to understand that they give the winds a difference voice. It's refreshing to hear the winds sing small tunes rather than the usual blatant howling or the uncalled-for whispering of your name (wait wait i'm not psycho i swear that's supposed to be funny in its melodrama!). Anyways if the city winds are to drive anyone insane they would do so with or without chimes.

Stadhuis

Rotterdam city centre has several bell towers that ring loud without any winds. I can think of 3 main sets right now. There are bells at the Stadhuis (they play the Westminster chimes which I love), and there are bells at the Laurenskerk. There are bells at the World Trade Centre, when they ring they ring for a long time and their sounds have my favourite echo texture. When all these bell towers ring at the same time they speak to each other in a language only buildings know. I was in Taipei in the summer and in that city there's no tradition of the hourly striking bell tower, but the city has a lot of constructions going on, and wherever there's a construction site there is a constant metallic something-hitting-against-something-else. Gong, gong. It's also a language only buildings know, but maybe in a very different dialect.

Rotterdam Coollection 002

Coollection, a portmanteau, is the collection of cool things. I have coined the term one day and it had a geeky sound to it that I am quite fond of. These are blogposts where I share a collection of extraordinary online items related to Rotterdam. The Coollection may include photos, videos, websites, sounds, and anything that register as 'cool' in my book. Now that we know what this is, let's get to the cool stuff.

Bart van Damme is a Rotterdam-based photographer who takes very good pictures. He's been doing this for years so you can find photos of scenes of the Central Station construction etc. He does a lot of urban architecture and landscape shots and they are phenomenal, he also shoots a lot of industrial sites that you wouldn't usually go to. But even when he shoots at places that I do usually go to, his compositions make the regular street corner appear grand and majestic. This picture of the Pleinbioscoop at Museum Park, for example, I walked passed here during the summer many many times, but I never thought it could be captured like a shot out of a Kubrik film. You can look through Van Damme's material online and, if you wish to, buy his prints and books.

Here's a video of a Ferrari F430 racing through Rotterdam's streets during VKV Rotterdam City Racing 2014. I'll admit I have experienced more car racing from video games than from actually watching cars race. So maybe it's just me who feels that the video makes our city looks like a level in a racing game. Anyways game-like or not, this video feels surreal as you watch the Ferrari drive through our city in directions (and speed) that you cannot usually drive in.  I linked a video of people inline skating in the city last time, and it was fast, but this is FAST. And loud. And throbbing.

Markthal 360 Panorama

screenshot from markthalrotterdam.nl

The Markthal had been in construction in Rotterdam's Blaak for sometime. In a previous blogpost I have briefly used this construction as an example to make a note abot realities.  Now the Markthal itself had become a reality, soon to be officially opened by Queen Máxima on the 1st of October. This arch is a multifunctional building that include appartments, horeca establishments and a large market in the centre. It's also been getting news coverage for having a ceiling that possesses the WORLD'S LARGEST ARTWORK. Created by artist Arno Coenen, the graphic artwork Horn of Plenty can stretch out to cover two football field. In the future they also planned to project 3D animation onto this ceiling. Click on the title above to navigate a 360 degree panorama from the centre of the building and witness the wonder!

In fact, because of its impressive ceiling art, some promotional/journalistic text went as far as calling the Markthal the SISTINE CHAPEL of Rotterdam (which I think is funny because the Markthal is built right next to Rotterdam's actual most historical church, the Laurenskerk). The Markthal had also been referred to as Rotterdam's new food Walhalla. Such is the age of remixed cultural meanings and metaphors.

Nesselande's Light Transmitting Concrete Cubes

We have all heard of concrete jungles, but have you ever imagined a Light-Transmitting-Concrete jungle? What does that even mean?

I read about these Light Transmitting Concrete (LiTraCon), it's a building material combining concrete with optical glass fibres. While maintaining the hardness and weight of concrete, it lets light shine through like traditional asian paper wall. According to the LiTraCon company website, as the optic fibre hardly loses any light through its length, the LiTraCon material is capable of light-transmittance for thickness up to 20 metres. The material catches a unique balance between heavy and light properties and I thought it sounded really exciting. Imagine seeing something lights up through 20 metres thick of concrete! 

And then I found out that the engineering firm Vormtech used this material in 2011 to build street furnitures at a location near the Nesselande beach, to the north-east of Rotterdam. Naturally I had to pay a visit. There were 6 of these LiTraCon cube fixtures along the short Kosboulevard, marking corners of the regular concrete benches. Each of these is a LiTraCon case with light source placed on the inside, and with a fixed metal lid covering the top.

I can see that there is already plenty of regular streetlights in the area, and the way they set up the LiTraCon cubes here is less for illumination and more for decoration. I like the enchanted-runes vibe these cubes give out, it looks like they are inscribed with holy scripture. I like that it's pretty much impossible for external forces to break the lamp inside because they're protected by concrete ( The lamp itself might bust or malfunction though. This was possibly the case with the one cube that was off). But at the end of the day these cubes don't demonstrate my favourite thing about LiTraCon: the way you can cast shadows through it (as sensually presented here).

http://retaildesignblog.net/

When I first saw this material do shadows my intuition speaks shadow puppet theatre. Did I mention LiTraCon also allows colours to shine through? It promises all kinds of exciting visual presentation and connection between both sides of a concrete wall.

From what I've read, LiTraCon cannot (yet!) replace good old concrete because it is way more expensive, so we're not going to see entire concrete structures made of this stuff any time soon. But I'll be very happy to see smart applications of materials like this in cities here and there, infusing the concrete jungle with some visual diversity that any so-called jungle should rightfully include.

p.s. originally I wanted to do this blogpost on new technologies and lights, and I was gonn include another location. I tried to visit Daan Roosegaarde's Dune 4.2 interactive installation at Kralingen's De Esch, but the installation was apparently not there any more. I later researched more carefully and found that they removed Dune 4.2 in early 2013. I's been a few years since they set it up (2009) and it makes sense that higher-tech installations don't stay at one location forever.  It's a shame though, I always wanted to see it since it looked hella dope extremely captivating on video.

Rotterdam Coollection 001

Coollection, a portmanteau, is the collection of cool things. I have coined it just now and the word has a geeky sound to it that I am quite fond of. This is a new kind of posts I'm doing on this blog, where every once in a while I'm going to share a few cool Rotterdam items that I've found on the Internet. Videos, pictures, websites, you name it. Actually I'll name it. Whatever. I'll also put down a few words on why they're cool so you'll have greater insight into my taste in cool things.

These guys are doing a project where they travel around the world to shoot rollerblading videos in cities. Sometimes they do tricks. Sometimes they're just fast. They also make cities look very good. In this vid they skate through some of Rotterdam's best-looking places and it's stimulating to see our familiar sceneries re-defined by alternative sets of movements and perspectives. The tracking shots are the best parts. Without rollerblades it would be very difficult to experience these spaces in motion. I mean, sure, you can walk through the Beursplein underground passage, but that's pretty slow.

Brett Bogart, now occasionally dubbed the Netherland's Justin Bieber, is a nascent teen-pop sensation from Brabant. He shot this music video for his new single Rooftop on top and around Rotterdam's Schieblock. The video has bright-coloured teen fashion, some cartwheels, several back-flips, and lots of dancing on the rooftop. It's kind of surreal that people born in 1999 are becoming pop stars now. In 10 years' time people born in 2009 are going to be pop stars. Wow. 

snapshot from youtube

Anyways Rooftop is great because while wishing for this video to be an international youtube hit, Brett (and most likely his marketing people) looked for international appeal, and decided on an urban metropolitan feel. Boyz and girlz partying on a rooftop surrounded by sky scrapers, these are colourful kids in a grey city, free and all-so-happy. Naturally they had to film this in Rotterdam because it is the only Dutch city that can pull off this look. After the war, Rotterdam was designed and re-built as the American-styled city of the Netherlands. It had been dubbed accordingly our Manhattan aan de Maas. It is, then, only fitting for the Netherland's JB to shoot his video here.

ikRotterdam is 3 artists who draw snippets of Rotterdam. They do places, people, objects and whatever else they like. The art is really cool and they make great use of colours to demonstrate that the city doesn't feel so grey after all. The buildings look alive. The human portraits look warm-hearted. They tag each drawing with the area in which its subject matter was seen (Centrum, Delfshaven etc), so you can go and try to find it as well. Their tagline is "I don't need to go on vacation because I live in Rotterdam". It's pretty much how I feel too, but they express it with a charismatic artistic style I wish I had. You can like them on Facebook to get regular updates. I did.

USB dead-drops, physicality and secretly-sharing

When I saw Breaking Bad a while back, one of my favourite things about it was the physical details of how illicit activities can happen in plain sight without anyone noticing. One of those details was the dead-drop sequence where they moved small amounts of meth and money by having different people dropping and picking them up at obscure locations around Albuquerque, places where no one would ever check. 

Beyond the TV screen, dead-dropping is a technique that can be (and is) used in real life. Criminals, spies, ninjas and any other personnel of covert operations may be expected to make use of this practice every once in a while to transfer letters and packages. How many of these folks are active in this city?

Dead-drops are one example of the many alternative communication possibilities our urban spaces can offer. It signifies a hidden layer of communicative functions only available to those who know about it. There may possibly be infinite numbers of these layers that you don't know about. Given the way perception works, you can never know how much you don't know. Take the case of language. I don't know Morse code. How do I know if everyone around me are not discussing their murder schemes every time they blink their eyes? You never know with these ninjas. They can be anywhere, anyone, at any time.

Here is something I do know about. Aram Bartholl, a media artist, had taken up the dead-drop name for a project in which he installed USB flash drives in random locations in NYC in 2010. He literally sticked USB drives into brick walls and patched some cement around them to keep them intact. He called them USB dead-drops. These dead-drops are like the traditional ones described above except that they are digital. It is a digital communication network that is anonymous, locally-based and offline. If you know where one of them is, you can go there and upload data onto the drive and also download whatever data that's on it.

I think it's a pretty cool idea, many others thought so too, and since 2010 people around the globe had taken up the initiative to install USB dead-drops in their own cities. It's pretty easy to install one, and if you wish to you can submit its coordinates onto the map on deadrops.com. I have checked out some of these coordinates in Rotterdam, here are pictures of their current conditions.

On the Erasmusbrug

At Westplein

 

Witte de Withstraat

A part of the excitement in this initiative, for me, is its emphasis on physicality. It is intuitive for me to physically go somewhere and drop off or pick up a message. The travelling to that specific spot is a part of the communication, as is the location itself. While modern communication technologies had significantly cut down the time for messages to travel, it had also completely cut down actual physical travelling OF or FOR these messages, both of which could have carried a lot of extra meanings. By (re)-placing data in the real physical context, we re-include the spatial-locational element into communication. This is not unrelated to the oft foretold Internet of Things, but in the case of dead-drops, things are not connected via the Internet. Actually a dead-drop and your personal devices can only be connected by your movement between/to them. They are connected via you. It's the Internet that is You! (I'm sorry I'm pretty bad at coming up with theoretical catch-phrases)

--
You may have noticed from the pictures that some of these drops are broken. When you place anything in public you risk vandalism and natural wear. The other thing you risk is security. It's quite possible for an open USB drive to be infected with malware, which can then infect every device that comes into contact with it. This is a pretty serious problem and it is what stops many from connecting their devices to a dead-drop. There is a political discussion in this: can you trust an anonymous people to use a shared tool/property and not ruin it for each other? Instead of approaching it as a ethical-philosophical debate regarding Hobbesian social-contracts etc, a relatively easier way out is to solve these problems through design.

First off, to a limited extent, the problems cancel each other out. As per its current standing, I think USB dead-drops are more of an experiment/artistic-statement rather than an attempt to create a functional information infrastructure, and these guerilla data storage devices are not designed to last. They break pretty easily, and the short life-span of a drop may be a protection mechanism in itself. If a drop is new and fresh, it might not have caught any malware yet. If a drop is old, it's probably already broken anyways and will not be able to infect anything. This system doesn't guarantee security, it guarantees nothing but the fact that an infected drop will not serve to infect many more devices. This limits the scope of damage.

A security measure users could take is to actually keep the discreet location of a dead-drop a secret between a small group (i.e. not publish its coordinates on a website). If only trusted people will have access to a drop, you can then trust in these people's judgement and assume that only trusted devices will be connected to it, thus keeping it clean. This is a form of social security.

If we are to solve these problems through improving/changing the hardware, maybe wireless alternatives can also be a more costly option. Small servers can be placed in a secluded and protected environments, not (easily) physically reachable but can be connected to via wi-fi when you're in its proximity. You go to that pavilion in the park where you always meet up with your friend. You take out your phone, connect to this local network that only you know about, and download a new mini-video that he left for you there. By the time you are watching this video I would already be in Ireland, he said so in his webcam recording, I suppose this was an Irish goodbye. You delete that video from the local server and cry. Your friend was also your boyfriend but now it's complicated. The problem with this scenario is I can't really figure out a way to constantly supply power to that server. Only bring portable power supply to the server when someone wants to access it, maybe? In any case this server-approach loses some of the guerilla charm of USB dead-drops.

--
Since we're talking about charm, let's get back to dead-drops' social security tactic for a sec. I want to end this on a note about trust. Maybe one of the few people who use your drop will judge wrong one time and infect the drop. Maybe some of these people are malintentioned from the very start and planned to compromise your device. All of these are possible, but consider it is known that the NSA can alter hardwares for surveillance purposes as they leave the factory, consider that personnels like Edward Snowden were trusted with access to your emails, consider that just visiting FBI targeted websites puts the security of your machine at risk. I think it's reasonable to trust local people you know in your personal network, at least as much as you trust someone you've never met on the other side of the Internet, thus trusting a secret small-user-group dead-drop as much as you trust the Internet (if not more). And if a small group of intelligent people trust each other, they should be able to share a secret dead-drop for all kinds of purposes pretty successfully. Based on trust, it'll be a very communal kind of sharing, possibly ritualistic, possibly tribal.

Not Rotterdam: The longest distance between two metro stations (Taipei)

wikipedia.com

I haven't been updating this Rotterdam blog because I haven't been in Rotterdam recently. Instead I'm in Taipei trying to look at as many things as possible. I grew up in TP and it's likely that on a subconscious level this city had curated many of my urban fetishes. Or, in the phrasing of an architecture book I flipped through in a bookstore today, Taipei had taught me my urban mother-tongue. I like car exhausts. I like messy street signs. I like natural colours situated in grey. I like cheap & efficient public transport. I like 24/7 food. I like busy but warm-hearted people. There is a lot to think about and it's taking me a while to figure out where to start.

We can start with metros. It's a good place to start. My very first experience of metro travelling was with Taipei MRT and it's still my favourite metro system today. The Wenshan line is completely automated and runs on elevated rails through the city, it's almost like a theme-park scenic ride. The other lines are mostly underground, they are inviting and cozy and efficient and clean and are everything that metros should be.

eurotrib.com

A few weeks ago there was a metro tragedy in Taipei that shocked the city greatly. While travelling on a carriage between two stations, a mentally disturbed university student whipped out two knives and stabbed 28 people,  killing 4 of them. This kind of crazy slasher incident had never happened before in Taipei and many grew paranoid. After the attack, for a while the police assigned special-force operatives equipped with sub-machine-guns to patrol metro stations in order to scare off any similar attempts. A lot of the city's inhabitants felt that this was inappropriate and looked like a police state. If anything it only made the metros scarier.

The emotions had since settled down, the sub-machine-guns are removed and when I took the MRT today it wasn't very scary at all. Anyways I guess what matters the most for commuters is not how safe the metros actually are, but rather how safe they feel about it. 

--

When reading about the young attacker and his methodologies, a specific item drew my attention: He had allegedly observed the MRT system very thoroughly to select the time and place for his crime. The ride between Longshan Temple Station and Jiangzicui Station takes a total of 3 minute and 46 seconds, it's the longest time between any two consecutive MRT stations in Taipei, and this guy figured that between these two stations he has the longest window to stab the maximum amount of people on a moving train before they can get off the carriage. He did end up stabbing a high number of people, and for his purpose this was an effective plan. If he chose a random ride between two random stations, it is likely that his crime would have been of a smaller scale.

At the observation stage he had allegedly timed the metro ride between every MRT station with his wrist watch, to know exactly how long each ride would take. This sounds a lot like something I would do for this blog. Luckily I am not a psycho murderer and my observations do not serve any sinister end. If a psycho murderer does find this blog, however, and were to use my urban patterns to design a ritualistic murder spree in Rotterdam, there is little I can do about it. Urban observations consist of methodologies that produce data, which can then be used to to generate meanings that may in turn inspire further actions. Starting from the generation of meanings, the process gets dynamic and can possibly be volatile. Texts such as this one only offer potentials.

Rotterdam Beurs metro station

When I get back to Rotterdam by the end of the month I hope to also measure and record the time it takes between each metro station. I will then also find out which journey between two specific stations takes a longest time. The practical implications is that during this journey the metro carriage is its own world, for a minute or two segregated from any external authorities or control. It forms a temporary stand-alone space that can develop its own rules. The tragic murder of innocent people is one extreme development, but it is certainly not the only possible development. What else can people do with the metro's momentary social pocket-reality? Here are a few ideas:

1. Practice radical politics
-Leftist, rightist, anarchist, any
-Distribute slogans and pamphlets
-Start your own country, start your own non-country
-Run this (non)country for 2 minutes

(The Netherlands is pretty open with its freedom of speech, and people can often practice political communication without being censored. This is not the case in many countries, in which the metro pocket-reality is more relevant for political actions. In some countries advocating gay rights is considered to be radical politics. If I were a gay man who would like to kiss my boyfriend on the metro as a political statement, in a country where this is taboo, for example, I should rather do it between the two stations that have the longest metro ride between them so we can have the longest kiss.)

2. Practice radical cultist religions
-Evangelism
-Worship & rituals
-Being possessed by a spirit who will use your mouth to speak a prophecy. (S)He has over 2 minutes to do it!

3. Play very very loud music, play very very vulgar music
-"Abrasive", "annoying", "that's not music that's just noise" etc

4. Perform very very loud theatre, perform very very vulgar theatre
-I imagine some form of cabaret

5. Perform an actual orgy
-Variety of participants
-Different genders and sexual orientations

6. Consume drugs
-Alcohol: we already see this sometime
-Others

7. Violate copyright laws
-Screen a part of a movie
-Share other copy-righted arts for free

8. Advertise for cigarettes and other items that are not allowed to be advertised
-Advertise in purposely misleading fashions targeting children
-Subliminal messaging

9. Talk about my stupid poetry
-Usually no one can stand that sappy tripe, it's basically a crime in the regular social reality, but I imagine a setting in which I can indulge myself the poet's sentiments for two minutes. At the beginning of June I was writing a pathetic song called Season Finale but then oh wait wait wait wrong blog again

10. Combine any 2 or more of the above

--
Some of these actions are not necessarily what I would like to see or what I would enjoy. I would be quite uncomfortable if someone is too drunk or too high on the metro, for example. I would also be uncomfortable if anyone practices hate-speech loudly on a metro carriage. The purpose of this blogpost is to point out that if one or more passengers plan to perform any of these actions on the metro, they can choose to do so between the two stations that have the the longest journey time, so as to perform the action for as long as possible before being forcibly stopped by law-enforcement personnels or any external actors (or before loosing the audience). Such is the possible implications of the time-span. Whether and how these actions would offend or disturb other passengers is a different discussion. Why do I smile if I see a gay couple lightly kiss on the metro, but would frown if I see a group of people having coked-up sex while worshipping an ancient fertility god? Does it make a difference whether these actions are performed on a moving metro carriage or any other public/private space?

For one thing, the actual performance of said coked-up sex on the metro would stimulate us to think about the issue. More possibly, just knowing that the specific metro journey takes a relatively long time can stimulate us to imagine said coked-up sex, or any other things we can do with this time. I have listed drastic options, but you can very much also do things like holding the hands of the person beside you through the longest metro ride.

--
Update: Since I've written this post I have travelled between Longshan Temple Station and Jiangzicui Station two times. Both times my friend timed the journey with a stopwatch and the travelling time is consistently 3 minutes 10 seconds. Maybe they have speeded up the ride? Maybe the news article was inaccurate? Maybe the murderer was too disturbed to measure correctly? Many maybes.

Update: In November 2014 I have found the two Rotterdam metro stations that has the longest distance in between.
