T-Motor was the class designation given by the New York Central to its ALCO-GE built T-1a, T-1b, T-2a, T-2b, and T-3a electric locomotives. The T-Motors were the New York Central's second electric locomotive purchase after the original class of S-Motors. The T-motors continued on in service with the New York Central and a few continued on with the Penn Central after the 1968 merger.
