The Q class

Class Q

A series of 12 4-6-2 locomotives built by Baldwin. They had 8-wheel bogie tenders.

Ordered from Baldwin due to the delay in delivering the P class caused by the WWI. During WWII all except 212 were taken by the Japanese for the Siam-Burma line. Nine were eventually returned to FMSR where they continued in service up to 1959. The following photograph of 511.02 is from my collection but I do not know the original source.

Above: FMSR 206 and below: FMSR 212 departing from Kuala Lumpur with a northbound express. Both photographs reproduced with permission from the Stephenson Locomotive Society, they are thought to be from the H M le Fleming collection.
