SR W class

what is it?

The SR Class W were 3-cylinder 2-6-4T tank engines designed in 1929 by Richard Maunsell for use on the Southern Railway. They were introduced in 1932 and constructed at Eastleigh and Ashford. The class was intended for short distance, inter-company/regional freight traffic transfer in London, and were standardised with parts from the N, N1, U and U1 classes.
