If you’re a frequent user of the Metro in Washington DC, ITMT has developed an invaluable app to help your public transport experience. The app called DCMetro, will allow you to easily view any disruptions to the metro lines, check arrival times, find the closest station to your current location, give you a map of the current system as well as quick access to Twitter updates and RSS feeds concerning the rails. If you plan on getting around Washington DC on time with the Metro and you use a Windows Phone 7 device, this app is pretty much a no-brainer to get. It is available now on the Windows Marketplace as a free download.
