Well, I have written my second WP7 app. This is a useful app for riders of the S. Florida Commuter Rail system known as Tri-Rail (see http://www.tri-rail.com).
The app will let you locate the nearest stations using the WP7's GeoLocation system to determine your current location. It will show the nearest station North of you and the nearest station to the South including the distance to the stations in miles.
The list of all stations can be displayed and select one to see the details of that station such as the address and the times the trains will arrive during the day. There is a button to click to display directions to the station using Bing to help navigate you there.
The next arriving Northbound and Southbound trains are displayed with the number of minutes until they arrive.
Select one of the stops at the station to see information about that train and all its other station stops with arrival times.
There is a fare calculator that will determine the fare for the train ride. Fares are based on the distance traveled (by zones), whether it is a weekday or weekend rate and the type of travel (one-way, round trip or one of several other types).
Finally, there is an info screen that displays some information, web page links and the About screen.
For more information, click the image to get to the marketplace and the app’s home page.
