This was based on the BR Mark 1 corridor all-steel coach.
The model was moulded in several parts. The body with its cut-out windows, a roof that clipped onto the top, mounted on two bogies. There was more than type of coach, some were standard corridor coaches, whilst some showed the window for a toilet compartment at one end.
Body detail included sliding ventilators above the windows and handles on the doors. Bogie detail included the side frame, coil spring and journal box.
The body was painted crimson, the roof was silver. There may have been a production run painted in southern green, which did appear with the Treble-0-Lectric.
The bogies were different castings, the leading one had a pin and the trailing one had a towing slot.
