i-Metro Content Usability
Public Transit trip planner for over 300 cities worldwide. Covers mainly rail systems plus the bus systems in a few major cities. Barebones interface requires you to key in the name of your departure and arrival stations. Partial station names are OK and you will get a pick list if you enter something ambiguous. Gives the route and tells you how long the trip will take. Doesn't tell you when the next train will arrive but does warn you if there is no service at the time specified.
