CR 2F 0-6-0 No 57339 on the Kilin branch train at Killin in c1953. The loco was certainly running around without signs of ownership on its tender at the end of 1951. The pre-grouping Brake Composite coach (I am pretty sure it is of Caley origin) may help date the photo as Stanier stock was used later.
