B unit
Vulcan produced a wide variety of steam locomotives, mostly small but some with up to eight driving wheels. With the advent of internal combustion technology, the firm began producing small locomotives fueled not only with gasoline, but also benzine, alcohol, kerosene and naptha. Vulcan produced its first diesel locomotives in the 1920s; a total of 54 diesel-electric switcher units (each weighing or more) came out of Vulcan's shops between 1938 and 1954. Its largest unit was a B-B unit built for Carnegie Steel Company in 1944. It also constructed the TCDD 56301 Class for the Turkish State Railways in 1947.
