The Bombardier ALP-45DP is a type of single cab dual-mode locomotive operated by New Jersey Transit and Exo.

[30][31][32] On June 28, 2019, Bombardier announced that the first car body from this order was inspected and approved for final assembly.

In 2019, NJ Transit unveiled locomotive 4519 painted in a heritage Erie Lackawanna scheme.

[19] The first unit, AMT 1350, arrived in Montreal on June 9, 2011, after being shipped to Newark and then moving north to its new home.

However, in January 2020, the electrified portion of the Exo network was permanently closed, so the locomotives now operate exclusively in diesel mode.

[40][note 3] Design requirements included weight less than 288,000 lb (131,000 kg), length less than 75 ft (22.86 m), and EPA-compliant emissions.

[45][46] The locomotive uses four 1,300 kW (1,700 hp) MITRAC DR 3700 F[note 1] fully suspended, bogie mounted traction drives to reduce unsprung mass.

[45][50] Normally, one provides a 3 phase, 480 V 60 Hz 1100 kVA supply for head end power, while the other provides several 3 phase variable voltage, variable frequency supplies (up to 480 V 60 Hz) for the traction motor fans, transformer fans, and inverter cooling circuit motors.

This is most likely to prevent the loss of power during the transition to diesel mode with a limited amount of wire left.

[55] The locomotives are within Amtrak's A-05-1355 structure gauge and meet CFR and AAR crashworthiness standards.

[24] The bodyshells of the locomotive were constructed at Bombardier's Wrocław site, the bogies at Siegen, and the alternators at Hennigsdorf factory.
