So, this is what I've observed from last month till now, don't know if this is accurate:
* The Northeast Corridor uses Bombardier ALP-46 with Bombardier Comet Cars or Arrow cars
* The Raritan Valley Line uses Bombardier ALP-45DP with Bombardier Multilevel II passenger cars
*The North Jersey Coast Line and Morristown to New York uses either a ALP-45/46 with Bombardier Comet cars, Hoboken are diesel locomotives (Morristown to NY uses Multilevel cars)
*The Gladstone Line uses Bombardier Multilevel II cars with either a ALP-45 or 46 or Arrow cars
*The Mountclair line uses a ALP-46 with Multilevel cars to NY, Hoboken are diesel powered locomotives with Alstom Comet Vs
* The Main Line is either a Comet V or Multilevel cars
* All diesel locomotives with Comet Vs are on the Bergen Line and Pascack Valley Line
* Atlantic City line comets are Bombardier and Alstom comet Vs and a diesel type
*The Port Jervis Metro North uses a F40 or G40 Locomotive with Alstom V cars
