The earlier 0-8-2T radial tanks in localbahn service (Locobase 6034 and 5814) were the source of this trio, but the later engines had slightly bigger boilers, taller drivers, and weighed more. They entered service in 1935 (84-85) and 1936 (86), survived World War II, and were only retired in 1960-1961.
