This DLC idea comes from me who lives near one of the New Jersey Transit Riverline train station. This line stretches from Camden N.J. to Trenton N.J. The passenger locomotive is a Stadler GTW 2/6 DMU. Here is a picture of it. Here is a website that tells you almost everything about that line. http://www.jtbell.net/transit/Camden-Trenton/ Here is the map and shows all the station. Here are some interior pictures. Here is the train in action . . In conclusion, this route could be a big hit for people who like the american passenger trains.
