Burma Railways class C
Burma 1896 4 produced
In 1896, Neilson & Co. delivered two small 4-4-4T tank locomotives to the Burma Railways, which were designated class C. These had a axle load of less than eight tons and were fairly flexible with two two-axle bogies. They were oil-fired, but also had a small coal reserve. Their large firebox in relation to the tube heating surface indicates that they were well suited for commuter traffic with rapid acceleration and many stops.
