FMSR Class K - New K

New K (1928—1970s)

As the K Class designation was vacant following the retirement of the sole K Class locomotive in 1926, a new series of locomotives was introduced in the following year to take its place. Bearing FMSR numbers 151 to 161, the "new" FMSR Class K was introduced in 1928 for use for the then newly opened East Coast Line that served the East Coast of British Malaya, with 11 in total built. The Class K was delivered in two batches; the first in the form of seven locomotives built by Beyer-Peacock in 1927 (works numbers 6373 to 6379) and delivered 1928, followed by another four by Robert Stephenson in 1929 (works numbers 4013 to 4016) and delivered 1930. The locomotives were distinguished as K1 for those from the first batch and and K2 for those from the second batch.

Based on the earlier Class L, the Class K was a 4-6-2 tender locomotive with an 8-wheel bogie tender. The first batch of Class Ks were essentially improved version of the L Class; further improvement were made on the second batch. With an overall length of 56' 4" and cylinders measuring at 17" by 24", the Class K weighs in a total of 91.3 tons (55.5 tons from the locomotive and 35.8 tons from the tender).

While records exists of three Class K1s and three Class K2s shipped to Burma during Japanese occupation in World War II for use in the Thailand-Burma Railway, the entire K Class fleet was accounted for when it was renumbered in 1946. The K1 Class was entirely withdrawn between 1958 and 1959, while the K2 Class remain in use well into the 1970s, when all steam locomotives were withdrawn.
