An app to track the location of trains on the Cleveland RTA's Red, Blue, Green, and Waterfront commuter train public transit lines. It uses a simple interface showing if trains are at or between stations as well as the direction they are heading. Freshness of data is indicated by the color of the trains identifier. White is new (< 30s ago), grayer is older. After 120s the train is no longer shown as it has likely gone out of service.
