The Burma Railways class As was built in 1916 by Beyer, Peacock & Co. for light suburban passenger traffic. These eight tank locomotives had the wheel arrangement 4-6-4T and a slender boiler. The Belpaire firebox was located between the second and third driving axle, but was concealed by the water tanks which went forward up to the smokebox. No. 144 is now on display at the main station in the former Capital Yangon. It now carries the letters “MR” instead of “BR”, since the country has been renamed to Myanmar.
