Baldwin Class 10-12-D

The Baldwin Class 10-12-D was a class of narrow gauge 4-6-0PT steam locomotives built by the Baldwin Locomotive Works in the United States for the British War Department Light Railways, which used them in France during the First World War. About 495 were built between October 1916 and April 1917 for 600 mm gauge track, and the design grew out of earlier Belgian and French 600 mm military locomotive types that the Baldwin drawing office reworked into an American version. Some of the class served in Egypt, Sinai and Palestine, and after the war many were sold to railways in France, Britain and India, including the Welsh Highland Railway, the Glyn Valley Tramway and the Ashover Light Railway. Several survive in preservation, in the United Kingdom, Australia and Greece.
