When two coaches were coupled, a curtain was used to cover the inside surfaces of the diaphragms and faceplates. On the coach end was a wooden doorframe this was connected to the faceplate by a flexible diaphragm made from plasticised asbestos. At the bottom it was riveted to the buffing plate, whilst the top was supported on the coach end by two telescopic spring units. These gangways consisted of a flat steel plate, having a large aperture for the passageway. In the design of their new Mark 1 coaches, British Railways decided to standardise on the Pullman type in view of its resistance to telescoping. Two of the pre-BR companies (the GWR and the London, Midland and Scottish Railway) favoured the British Standard gangway, whereas the other two (the London and North Eastern Railway and the Southern Railway) used the Pullman type. On the formation of British Railways on 1 January 1948, operators decided to produce a new range of standard coaches, instead of perpetuating existing designs-but the new types had to be compatible with the old. Some coaches needed for LNER or SR lines were given gangway adaptors, so that they could safely couple to coaches fitted with the Pullman-type gangway. įrom the beginning, the London, Midland and Scottish Railway used the British Standard type of gangway connector, with its "scissors" pattern as used by the GWR. From 1938, GWR coaches which were expected to need coupling to LNER or SR coaches were fitted with gangway adaptors, to allow the dissimilar types to be connected. In 1925 the GWR started to use the "suspended" form of gangway connection instead of the "scissors" pattern. In May 1923, the GWR introduced some new coaches on their South Wales services some of these coaches had British Standard gangway connections and screw couplers as used on many other GWR coaches some had Pullman-type gangway connections and Laycock "buckeye" couplers and there were some with one type at one end, and the other end having the other type. Ī GWR coach fitted with a British Standard gangway connection of the "suspended" type The GWR introduced restaurant cars in 1896 gangway connections were fitted, but passengers wishing to use the restaurant car were expected to board it at the start of their journey, and remain there: the connections were still not for public use. Some coaches intended for use at the ends of trains had the gangway connection fitted at one end only. The gangway connections of the early GWR corridor coaches were offset to one side. Passengers could still use the side-corridor within the coach to reach the toilet.
When the guard was not so required, he kept the communicating doors locked.
Electric bells were provided so that he could be summoned. Built to the design of William Dean, it was the first British side-corridor train to have gangway connections between all the coaches, although they were provided not to enable passengers to move around the train, but rather to allow the guard to reach any compartment quickly. In March 1892, the Great Western Railway (GWR) introduced a set of gangwayed coaches on their Paddington to Birkenhead service. Howlden was Carriage and Wagon Superintendent. The Great Northern Railway introduced the Gould-design gangway connection to Great Britain in 1889, when E.F. Among the first to use them was the Pennsylvania Railroad on the Pennsylvania Limited service to Chicago.
Pullman's vestibule cars were first used in 1887. In the event of an accident, the design also helped prevent cars from overriding each other, reducing the risk of telescoping. The vestibule prevented passengers from falling out, and protected passengers from the weather when passing between cars. For passing between cars, there was a passageway in the form of a steel-framed rectangular diaphragm mounted on a buffing plate above the centre coupler.
This practice was dangerous, and so Pullman decided to enclose the platform to produce the vestibule. Older railroad cars had open platforms at their ends, which were used both for joining and leaving the train, but could also be used to step from one car to the next. Pullman introduced his patented vestibule cars. This British locomotive has a centre buffing plate similar to that fitted to the lower portion of a Pullman-type gangway connection.
