Federated Malay States Railways 0-6-0 Locomotives in Malaya


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 14390)

Data from DeGolyer, Vol 63, pp. 157+. Works numbers were 54597-54606 in March 1921.

These tank switchers were delivered at the same time as the Moguls described in Locobase 3235. Unlike the latter, these were coal burners.

Locobase had not encountered such an explicit and lengthy order for builder's photographs as was laid out on the last page of this order.
