Japanese trains are scheduled to within 0.19 seconds

This is sort of disorienting for an American. This Discovery documentary shows Japanese commuter trains being human-driven to within 19 hundredths of second precision at a transit stop---as if they were musical instruments in a symphony. Nothing I've ever used as mass transit can remotely claim that level of repeatable timing precision.

Japanese transit is apparently so precisely scheduled that an entire genre of detective fiction apparently exists in which the reliability of the train schedules establishes alibis, guilt, and the opportunity for murder most foul...

From Gawker; a Discovery Channel documentary

(Edit: thanks to Radx for pointing out that Discovery screwed up claiming 19 microseconds precision...edited for math accuracy...)

> The conductor was off by 190 miliseconds

OK I could go for a train 19 microseconds late, but there is no way I am waiting around for 190,000 microseconds to pass

SFOGuysays...

Can you imagine what that would be like? to have a transit system so reliable that you could set your watch by it at every stop, around the clock?

Math aside... I wish the maintenance staff at Boston's MBTA were this diligent (and timely) with their trains.

An interesting bit from that Wiki link:
"It is believed that a contributing factor in the accident was the JR West policy of schedule punctuality. As a result of this, Masataka Ide, JR West adviser who played a major role in enforcing the punctuality of the company's trains, announced that he would resign in June 2005 at the company's annual shareholder meeting, with the company's chairman and president resigning in August."

Executives taking responsibility for things? Woah. An unfamiliar concept in America...

Arriving on time aint all it's cracked up to be.

If they get much more punctual than that (know exactly where they are at which time), they won't be able to know at which speed they go.

SFOGuysays...

Thank you for the correction!

Oh, Discovery.... 19 microseconds is 0.000019 seconds. The conductor was off by 190 miliseconds or 0.19 seconds. They missed by 10^4.

What gets me is the apparent investment in maintaining infrastructure. In the US we just kind of build it and leave it, and only in the last few decades does it feel like we're getting around to: "... Oh, yeah I guess we should check on that...?"

SFOGuysays...

I totally agree. It's incredibly sad. If the New York City subway system had run with this sort of precision through the 60s and 70s, the city might have never gone through terrible economic recession of the 70s...because the attraction of such an incredible infrastructure system is compelling for everyone.
