Burma Railways Fairlie No. 209 to 213
In 1900, Burma Railways received five meter-gauge Fairlie locomotives from Vulcan Foundry. They had two bogies, each consisting of three coupled axles with same-size cylinders. Their difference compared to earlier Double Fairlies was that they had two separate boilers which were not joined by a common firebox. This layout was sometimes called “modified Fairlie” in this time, but had nothing in common with the Modified Fairlies built for the South African Railways more than 20 years later.
Their fireboxes were of the Belpaire type and had Drummond cross water tubes which further increased their heating surface. Each firebox was fed by one fireman, so that three people worked in the cab. Most of the time, the locomotives took a separate water tender with them.
