With the announcement of the Morristown Line, including one of the most requested train types, the Arrow III, and the ALP-45DP add-on, the Arrow III and ALP-45 should be added to the Trenton route. Arrows operate services from New York Penn to Jersey Ave, and the ALP-45s head towards Bayhead. With the addition of these vehicles, we could see a more active route on the NEC.
You forgot about the RVL ALP-45DPs on Track 5. Looking at my profile picture it's the arrow III on Princeton Dinky service
