Fahrplan is a third party alternative to Nokia/HERE's Public Transport and has been consistently updated over the last few years, I've done a summary of the changes below. And you can grab it in the AppList Store, of course (where else?!) If you live in a supported country, of course. Still an impressive third party project though.

From the current description in the AppList Store:

A journey planner and timetable application for a lot of train and public transport lines in Europe, USA and Australia.

Fahrplan features:

• Plan a journey from one station/stop to another (with one via station if supported by provider).
• Select type of transportation (depends on provider).
• Real-time timetable information for a station/stop (with direction if supported by provider).
• Find a nearby station based on your GPS location (if supported by provider).
• Add station to favorites for quick access in future.
• Add journey to calendar.

Currently supported providers are:
* Germany (bahn.de) - supports via station and GPS location.
* Germany, Munich (mvv-muenchen.de)
* Austria (oebb.at) - supports via station and GPS location.
* Austria, Salzburg (svv-info.at)
* Denmark (rejseplanen.dk) - supports via station and GPS location.
* Switzerland (sbb.ch) - support via station, timetable with direction and GPS location.

Hopefully the AppList Store is working out for you all. See here just in case you haven't already got this installed or if this is new to you. Also, if you have custom firmware installed, make sure you tick the option in settings to show 'unsigned' applications, you'll see extra applications!
