The Indian locomotive class WM was a class of 2-6-4T tank locomotives used on broad gauge lines in India from 1942.[2][4][5] A total of 70 of them were delivered new, and another four were converted from existing class WV engines.[1]
The ten prototypes of the WM class, the first 30 production units, and the four WV class locomotives that were later converted to WMs, were built by Vulcan Foundry in Newton-le-Willows, Lancashire, England. The remaining 30 WM class engines were built by Robert Stephenson and Hawthorns in North East England.[1]
