Second hand four-wheel runners obtained for departmental use and never used in regular traffic, the first of these was equipped with sides and a platform upon delivery which has since been removed; one of these is currently stored on Road Zero at Douglas Station between two bogie runners with another to the side of the carraige shed in derelict condition.  A third purchased was fitted with a new floor and is at the end of Road Zero; all are fitted with handbrakes similar in design to M.78 but none are in condition to run.
