CommuterRailBoarding / TrainLoc

There are two applications which are a part of this repository, and run together in AWS.

• CommuterRailBoarding: uploads the Commuter Rail boarding status information to an Enhanced TripUpdates JSON file.
• TrainLoc: uploads the train locations to an Enhanced VehiclePositions JSON file. It also tracks conflicts where multiple vehicles are logged into the same trip.
