HKL 360 was built by Hudson Bros and entered service in July 1891 as a mail-van with second-class accommodation, numbered 28. It was coded and renumbered KL 360 in 1892. As a shortage of brakevans existed during early WW2, three of the remaining KL cars (360, 386 and 424) had a guard's compartment installed in the area previously occupied by the passenger compartment. The wagons were then coded HKL. HKL 360 was converted in December 1941, the first of the three cars to be converted.
