Diesel? Electric? Both? The ALP45-DP! (My 500th Video Post)

New Jersey Transit's ALP45-DP is a dual-mode locomotive based on the ALP46 and ALP46A platform, this locomotive can operate off the AC overhead catenary or as a regular diesel locomotive in non-electrified territory. Unlike their all-electric cousins, the dual-mode has only a single cab at one end and is a bit longer overall.

This video shows some of the units in all modes: mode change from diesel to electric at Newark Penn, in electric mode at Mountain Station, a mode change from electric to diesel at Newark Penn, then in diesel mode at Secaucus.
