Thanks, I'll have to try it out when the N900 hits.
To make it more universal, does it just use a jpg or gif file to scroll around on? That way the NYC metro etc can easily be added. The tricky thing is to actually use the graphic file and select a station and look up departure times.

I would guess that a database of lines with tube stations can cross reference each table to find where the changes are. eg.

Picadilly Line:
1 Cockfosters
... (intervening stations)
9 Finsbury Park
... (intervening stations)
13 King's Cross
... (intervening stations)
Green Park
etc etc

While for Victoria Line:
Walthamstow
... (intervening stations)
Seven Sisters
Finsbury Park
...
King's Cross
...
Green Park

The table would be equal where they both have Finsbury Park, King's Cross and Green Park so we know they are the change points. The number on the left denotes which station in order it would be.

I'm not sure if that's the best way of doing it, thinking just off the top of my head, but having a database like that could make it easy to load database/picture files for each metro around the world that people may submit?
