New York Governor Kathy Hochul announced that new 4,200-horsepower Siemens Charger locomotives received last year for testing by the Metropolitan Transportation Authority (MTA) will begin passenger service on Metro-North Railroad’s Hudson Line at the start of Climate Week NYC, Monday, Sept. 22. These new locomotives provide riders with even more reliable service while reducing airborne pollutants by 85 percent, all while producing 1,000 more horsepower than the current fleet.
The new locomotives will be able to travel farther under electric power than the current fleet of locomotives, the GE P32s, which operate under electric power only in the tunnels in and out of Grand Central Terminal, a distance of four miles. The new locomotives can operate in electric mode the entire 102 miles of Metro-North’s third rail territory, which extends to Croton-Harmon on the Hudson Line, Southeast on the Harlem Line, and Pelham on the New Haven Line. The new locomotives are compliant with Tier IV of the U.S. Environmental Protection Agency’s vehicle emission standards, significantly improving emissions and noise pollution in densely populated areas across the State of New York.
In 2021, the MTA’s Metro-North Railroad placed an order with Siemens Mobility for 27 Dual Mode Charger locomotives, known by the model number SC42-DM. These locomotives operate on both diesel-electric and third-rail electric power, enabling them to run on all of Metro-North’s non-electrified lines and switch to electric power for electrified routes, including in Grand Central Terminal. These locomotives are being manufactured at the Siemens Mobility rolling stock facility in Sacramento, CA, and delivered to Metro-North through 2027.
The purchase of these new Siemens Charger locomotives was funded by the MTA’s 2015-19 and 2020-24 Capital Plans, along with funding from the Federal Transit Administration (FTA).
