AMTK 2013 blasts past the ex-PRR tower as it brings up the rear of a northbound Acela. In the distance, an NJT local can be seen approaching.

Heat radiates all around the engine as NJT 4418 shoves a train out of the station and northbound to New York.

NJT ALP46 4611 eases under the old PRR signals at MP 47 and prepares to make a southbound stop at Princeton Jct.

NJT ALP44 4421 works hard accelerating the train northward through Princeton Jct. and on to NYC.

While a NJT train makes its station stop, AMTK 953 flies past southward, on a normally northbound track, with a three-car Keystone train.

Note power car on rear; otherwise, GG-1s couldn't have hauled electrically-powered Amfleet cars
