Problem in Tokyo

Ah, if all transport systems could be just as simple as the single line in Naha (beautiful place, by the way)!

Take the Ooedo line in Tokyo for example: it goes in some kind of an open loop from Tocho-mae to Tocho-mae and from there ends its route at Hikarigaoka. As for any "standard" line, MetrO gives the direction to take as "Tocho-mae" or "Hikarigaoka" (the end stops).

But this was too easy: the fact is that the directions displayed on the platforms are not always one of the the end stops, but are instead the closest of one of a few major stations along the line. This means that near the end of the "loop", the direction is Tocho-mae, but in the direction opposite to Tocho-mae (the one at the end of the line)!

You're lost at these explanations? So was I, until G. Montgomery took the pain to explain in long details. Now I understand the problem and I can see that the program "apparently" gives wrong directions. I'm still looking for a way to solve this problem but, in the meantime, be careful when MetrO tells you to "Take the Ooedo line, direction Tocho-mae": it just means the end of the line and not necessarily what you can see on the signs.

To be continued...

  1. Yeah, that line is a weird one. It's basically a big numeral "6", with Tocho-mae being where it meets itself. Tocho-mae has four platforms--two around the tracs at the end of the line and two around those in the middle. Just a thought: what if Metro listed something such as "Tocho-mae, platforms 1/2" and Tocho-mae, platforms 3/4" as separate stops, with a walk between them? (I'm not completely sure if the numbers are paired like that, but I can easily check.) Passengers do indeed have to walk either across or up-over-down to another platform if they're not continuing on to the next stop on the line in the same direction.
