The U34CH was a 3,600 hp (2,700 kW) passenger diesel locomotive built by General Electric between 1970 and 1973. In total, 33 U34CH units were built; 32 were built for the New Jersey Department of Transportation and operated by the Erie Lackawanna Railway and, later, Conrail, with the last unit coming as a later rebuild of a GE U30C for the New York MTA.
