Track Train is an iPhone app for commuters who take the Long Island Rail Road (LIRR) trains to New York City’s Penn Station. It displays what track your Long Island Rail Road train is leaving from at Penn Station, before it’s officially announced. Beat the crowd and go directly to the train platform, making sure you get the best seat.
The app is a side project that Alexander created to learn iPhone development. It was released in May 2016, and quickly became a popular app for LIRR commuters.
