That is an awesome suggestion, and to implement it will require
knowledge of the station layouts too. I am not sure if this stuff is
available on the web though, not to mention the challenge in
programming that algorithm into the web page.


You could use Roger Collings' "Way Out Tube Map" (printed, at
bookstores) for reference, which actually gives the ordinal number of
the carriage next to the exit or interchange for each station. But I
doubt that would be fair use of the map data unless you asked the
publisher or checked for yourself throughout the network.

According to the map, taking the 2nd carriage on southbound Victoria
line trains is even closer to the exit at Euston ...
