Charging Into The Future In Riverdale. During the week of February 4-6, 2025, MTA Metro-North Railroad/Siemens SC42-DM MNCW 302 tested on the Hudson Line. This testing included simulated stops, even when running on non-platform tracks. This dual mode locomotive is one of 33 on order to start to replace the railroad's General Electric P32s. Though similar to the all diesel design of the SC-44 and ALC-42, these locomotives also had to go to the testing center in Pueblo, Colorado for full evaluation before delivery to Metro-North. The locomotives are much quieter than their predecessors, and also significantly more fuel efficient while providing more power. On this night the train operated both in electric (third rail) mode up to around Croon Harmon, and diesel mode from there to Poughkeepsie. While the (present) GE P32AC-DM fleet changes from electric to diesel mode around the Harlem-125 Street Station, MNR has stated that this locomotive is designed to operate on third rail to the Croton Harmon area, where electrification ends.
