what is it?
The Midland Great Western Railway (MGWR) B Class 0-6-0 was a class of 4 locomotives built at North British Locomotive Company in 1904. In 1925 they were allocated Great Southern Railways (GSR) Class 646 / Inchicore Class J2. The MGWR Class B was an attempt at a more powerful 0-6-0 locomotive than the existing Class L. Like the Class A 4-4-0 which they shared some components they were weight restricted to the Dublin-Galway on the MGWR. They were rebuilt 1916/17 with superheating.
