Not true. http://www.bahn.de/p/view/buchung/auskunft/puenktlichkeit_pe... In August 2012, 99.1% of all stops happened within fifteen minutes of the scheduled time, 94.2% happened within five minutes. Looking only at long-distance trains, 75.8% of all stops where reached within five minutes of the scheduled time and 90.5% of all stops were reached within fifteen minutes of the scheduled time.

Not true. Today morning "We appologize bla bla", last Saturday evening "We appologize bla bla aprox. delay 60 min". In the end it was about 120 min. In Germany trains do have delays a way TOO OFTEN.

I don’t think you should respond to data with anecdotes. That’s not very useful.

You might be using a train connection that – for whatever reason (construction work, etc.) – is consistently late. Sucks for you, doesn’t mean train in Germany are in general late. Most are on time.

Slightly off topic, but when my brother was young he became obsessed with preventing train suicides and we actually came to the conclusion that placing an airbag on the front of the train would most likely (help to) resolve this issue. Based on our calculations it should be feasible to prevent death in at least a few percent of cases. Given that the biggest draw for train suicides is its near 100% success rate that w…

I also thought this is an almost impossible problem to solve, until a friend pointed out that on the Jubilee line extension (London Underground), it is solved. The edge of the platform at the newer stations is walled off from the track by glass. The platform doors line up with the train's, and open/close at the same time. So there's no access to the track at any point, hence no opportunity for "person under train".

They have those doors in many places in Asia also, but most of the trains people are jumping in front of in Japan are above ground and the stations are literally just platforms with a roof.

If you click on "Fernverkehr" you'll notice that actually only 90% of intercity-trains have been within the 15min window.

Every 10th train was late for more than >15min.

Yes, Regios may be better. That doesn't help when, for example, you need to catch a plane in a different city.

Real time arrival times for Boston subway (where available). http://wheresthembta.com I've never found the maps data viz particularly helpful.

Except for our beloved Green Line. The oldest subway in the country doesn't even know where it is--so it can't tell us.

Baaahahahahahahahahhahahahaaaaaa Train was 8 minutes late this morning and 3 lines were stopped. Probably due to the Typhoon yesterday causing scheduling problems but even on normal days Japanese trains are not the paragons of time-keeping the west seem to make them out to be (Although they ARE miles better than anything I have seen in the UK for instance.) [EDIT] Note: Previous poster downgraded the conviction of hi…

What is considered late there? If a train arrives within 6 minutes of schedule and departs within 11 it's considered 'on time' in my part of Australia.

In India, if a train arrives, it is considered 'on time'.

Apparently in Japan the cell phone reception is great even on the trains. Why don't ppl download an app where it figures out your gps location, speed and based on that figures out what train you are on. Then it finds others in the area with similar info to verify your data and puts it on a map. That way you know where the train is if you have these groups of people moving very fast close to the gps location of the railway tracks.

Platform doors are certainly possible above ground too.

Usually in Tokyo, they use chest-height barriers/doors for above-ground lines, e.g. currently the Meguro-line has these, and in the future, the Yamanote-line will. This doesn't make suicides impossible, but makes them more difficult to a degree which will certainly discourage many people (you can't just fling yourself off the platform at the last moment). [Some subways, e.g. the Fukutoshin-line, use these as well.]

A more problematic issue is stations which handle many disparate types of trains on the same platforms, which makes it much more difficult to achieve the consistent door positioning you need for platform doors.

One in ten seems pretty good to me. Everything else are completely unrealistic expectations.

As a guy sitting in a soba joint in Tokyo right now...I cannot imagine how much it would cost to put those doors on all the JR and Metro stations. It's certainly in the realm of prohibitive.
