The British Transport Commission organised this exhibition to show off progress under it's Modernisation Plan. On display were locos, coaches and equipment from BR and private builders. There were two DMU exhibtions, the following extracts are from the brochure, the cover for this is shown on the left.
The brochure obviously had to be produced in advance, the pictures it used were commonly used Works pictures. While exhibit 19 was described as being a buffet car, reports indicate that the vehicle exhibited was Trailer First W79471. If you have any further info on this, or any further pictures taken at the exhibition, I would be pleased to hear from you.
Inter-city Diesel Trains
Designed and built by British Railways
Interior design for buffet compartment: Peter Miller, ARIBA
Inter-city diesel trains have been in service between Edinburgh and Glasgow since January 1957. They are soon to run between Birmingham and Swansea. The trains are normally made up of six vehicles, with a total of 60 first-class seats and from 208 to 232 second-class seats according to the composition of the train. Two vehicles are powered and two are trailers. Two vehicles, which are not in new condition as they have been in service, are exhibited. One contains a buffet compartment. The power cars are equipped with two A.E.C. 6-cylinder 150h.p. diesel engines and with mechanical transmission. All power equipment was supplied by British United Traction Ltd.
Multiple-unit Diesel-mechanical Coach and skeleton body frame
Designed and built by D. Wickham & Co. Ltd.
Unusual construction methods are a feature of this diesel coach (Exhibit 21). The normal method of mounting the coach on a robust underframe has been dispensed with. Instead, the body frame (Exhibit 22) is constructed of solid drawn square steel tubing approximately 1/8 in. thick, electrically welded into one unit which is capable of withstanding the load and other stresses which may be placed upon it. The completed skeleton body and floor weighs only 5 1/4 tons.
Further weight-saving has been achieved by using 16-gauge aluminium for panelling both the inside and outside of the coach. The floor is of corrugated steel.
The power car is equipped with two Leyland 150 b.h.p. diesel engines, with mechanical drive through four-speed gear boxes. When operated with a trailer there is accommodation for 16 first-class and 109 second-class passengers.
