Sept. 22 marked the first day in passenger service on Metro-North for new Siemens SC42-DM Charger locomotives. The third rail ends at Croton-Harmon on the Hudson Line, Southeast on the Harlem Line, and Pelham on the New Haven Line. The new locomotives can generate 4,200 horsepower, about 1,000 horsepower more than the current locomotives. The introduction of the new locomotives, which are expected to reduce diesel engine air pollution by 85%, coincided with the start of Climate Week. The locomotives are being manufactured at the Siemens Mobility rolling stock facility in Sacramento, California, and delivered to Metro-North through 2027.
