Amtrak P42C Test Train In Manhattan. On the morning of Wednesday, April 23, 2025, AMTK 9700 (P42C, née-AMTK 184) led Test Train 870 (and trailed on Train 871) between Albany-Rensselaer, New York and New York Penn Station. The train is seen parallel to the West Side Highway with the George Washington Bridge in the background. This was the first time the rebuilt P42C led a train into New York Penn Station. Amtrak is planning to convert more P42DCs to P42Cs (cab car) to facilitate changing ends more quickly at terminals. As the P42 has a maximum allowable speed of 110 MPH, it is not suitable for Northeast Regionals, and will likely be seen mostly on trains like Empire Service.
