AMD-103 Genesis

Beginning in 1993, Amtrak took delivery of a new type of diesel locomotive dubbed the Genesis series and designated AMD-103 (Amtrak Diesel, geared for 103 mph). Three models are contained in this series: the P40BH, P32AC-DM, and P42DC.

The P40BH, the first locomotive in the series, develops 4000 horsepower. Its distinctive features originally included a fade-out stripe in the Phase III scheme, an extra rear hostler window to help with switching, a black post between the windshield panes, and strobe lights above the windows. However, many of the P40s are now in Phase IV paint with a silver windshield post, while the rear window and strobe lights have been removed, making them appear identical to the P42s. Like those newer units, some of them have been repainted into Amtrak's Phase V "wave" livery. The P40s are numbered in the 800 series.

The P32AC-DM was the second type of locomotive to be delivered. These Dual-Mode engines can operate using their diesel power plant or third rail electrical pickup, which is required in the tunnels under New York City. The as-built features, like those of the P40s, included a fade-out stripe, black windshield post, and the rear hostler window. A second order of P32s was received a couple of years later with the current features of Phase IV paint and a silver windshield post, though a hostler window was still present. Recently, some have been repainted into the Phase V paint scheme. The P32s are numbered in the 700-719 series.

The P42DC is the third and most recent type of AMD-103. Basically, this model is an upgrade from the P40BH, developing 4250 horsepower. The P42s came with solid Phase III stripes, a silver window post, and no rear hostler window. They have appeared in two versions of the Phase IV paint: the Northeast Direct type with a gray roof, and the Intercity type with a silver roof. Also, many additional P42s have been delivered in the Phase V paint scheme, distinguished by its wavy separation lines and large numerals. The P42 numbering series starts at 1 and continues up to 207, which forced the renumbering of the 190-series GP40TCs.
