Baldwin-Westinghouse electric locomotives

The Baldwin-Westinghouse electric locomotives were built jointly by the Baldwin Locomotive Works and Westinghouse, which had worked together since 1895 on alternating current railway electrification. From 1904 to 1905 they supplied locomotives carrying a joint builder plate to American railroads, notably the New York, New Haven and Hartford, with Westinghouse making the motors and controls and Baldwin the running gear, frame and body. The range included the single-phase No. 9 of 1905, the New Haven EP-1 passenger class of 1905 to 1907, the EP-2 and EF-3 classes, steeple-cab switchers for small railroads and interurban lines, and the Great Northern Z-1 class built for the Cascade Tunnel line.
