Interior

The main passenger saloons are unusual in that they have veneered panels running the whole length (most DMUs have Formica). First class is Rose Zabrano and second class is Lacewood. The bulkheads are all veneered to match. All beading and finishing strips are also wood, while other DMUs have alloy versions. The windows use standard BR components with sliding ventilators, and once had blinds in second class and curtains in first. Neither has been put back during restoration. Alloy luggage racks run the length of the vehicles, made up of hundreds of bars which, when come detached, contribute to the distinctive rattle that can often be heard inside DMUs. The ceiling is hardboard painted white, with false vents which, before being sealed up in the 1970's, leaked badly. Four 24V lamps (6 in the middle saloons) provide the lighting. The floors are covered in lino, which is laid on plywood which in turn sits on a corrugated base. The floors used to be asbestos and cork, however plywood replaced those when the vehicles were stripped of

asbestos after the heath risks were discovered. First class used to have carpet, but these were all removed in the 1970's and have not been replaced in preservation. Bolted through the floor are the seats themselves. They are of a high back type, not lower "bus styled" seats that many DMUs were built with, and have headrests in both first and second class. Second class seating consists of 2+3 with a gangway in the middle. First class seats are wider (2+2), have armrests, and are covered in a different material. All the original material the vehicles were built with has been lost and with no colour photos found to be in existence, it would be nearly impossible to reproduce the 1950's material. Therefore the seats are presented in 1970's condition, with a standard BR Blue material. M50455 had

been in service longer than M50517 so the seats were in good enough condition to clean thoroughly and re-use. Unfortunately the seats in M50517 and M59137 (see right) had suffered from damp and had to be recovered. Toilets used yellow colored Formica but the panels were painted white during the 70's & 80's. The toilet has been returned to original condition on M50517 and M59137's will as well. Fiberglass was used in the cab window surrounds and roof dome, and in covering various parts in the interior like the heater ducts in the vestibules. Heat was provided by two standard DMU Smiths heaters which produced hot air that was channeled into the saloons by heater ducts running along the bottom edges of the saloons. They "ducked down" under the floors where access was required (the passenger doors). The rear of the composite vehicles has another second class saloon

and the toilet. Brake vehicles used this space for the guards van which included double doors, a letter rack, equipments cupboards, fire bucket and guards seat (see right). It was painted yellow which later changed to grey. M50455 has had the yellow reinstated and has also had a guards table added by looking at 1950's works pictures (for some reason they must have been removed). The interiors changed little over their working lives as none of the class were part of the refurbishment program, but it seems at lease one vehicle had orange door panels fitted (see above left).
