The Steam railcars

9 2-car sets were planned in 1914 and 4 had been completed by 1917. It is not known if any more were built. In 1930 a single unit was supplied by Sentinel (built 1929) with 5 more 2 years later. These had 2-axle power bogies and 6 cylinders. A further 6 were supplied in 1938 with a larger boiler and 3-axle bogie, extra seating and a toilet in each coach. Four of the SR2 and three SR3 were in the KL area in 1955 with 252.05 active at that time.
