When the Great Western Railway sent out Britain's first train with a corridor connection between every carriage in 1892, the passengers were not allowed to use it. The gangways existed so that the guard could reach any compartment quickly; the rest of the time he kept the communicating doors locked.
That small irony sits at the heart of a much larger story. The flexible passage between two carriages looks like plumbing, but without it there is no dining car you can walk to, no bar car, no observation lounge at the rear, and no sense of a train as a single moving hotel. Nearly everything that defines a luxury train today depends on a strip of bellows and a steel plate that took the railways half a century to trust.
A train of separate rooms
For most of the nineteenth century a railway carriage was not a place you moved about in. British practice descended from the stagecoach: a row of compartments, each with doors on both sides and no connection to the next. You chose your compartment on the platform and stayed in it. Food meant a hurried station refreshment room.
American cars had open platforms at each end, but passing between them meant stepping across a shifting plate between two swaying vehicles, exposed to the weather and the drop to the track. Nobody would design a restaurant around it.
A queen who preferred to wait
The first British attempt at a connection was made for the most cautious passenger in the country. In 1869 the London and North Western Railway built a pair of saloons for Queen Victoria at its Wolverton works, to the design of Richard Bore. They were two separate six-wheeled vehicles joined by a flexible gangway, which the Science Museum Group, now custodian of the saloon, records as the first of its type fitted to coaches in Britain. The gangway was fitted at only one end of each vehicle.
The Queen, according to the standard histories of the royal train, preferred to wait until the train had stopped before walking through it. The technology existed; the confidence did not. The saloon became her favourite railway vehicle, a story told more fully in Queen Victoria's railway saloon.
Pullman closes the platform
The decisive step came from Chicago. George Pullman's company had already shown what a train could offer: the hotel car President in 1867, with meals cooked aboard, and the dining-only car Delmonico a year later, named after the New York restaurant. Once trains carried cars with different purposes, the US National Park Service notes, the industry needed a safer way to move people between them.
The answer was the vestibule. Developed by H. H. Sessions and his staff at the Pullman Car Works, it enclosed the end platform and joined each car to the next with an elastic diaphragm. Pullman secured the patents in 1887. The steel-framed passage sat on a buffing plate above the centre coupler, which had an unadvertised benefit: in a collision it helped stop one car riding over another, the lethal failure known as telescoping.
The first complete vestibuled train is generally dated to 15 June 1887, on the inaugural run of the Pennsylvania Railroad's Pennsylvania Limited to Chicago. The patent story is less tidy than the publicity suggested. Sessions filed his own application shortly before Pullman's, the courts later narrowed the Sessions patent, and Pullman went back to litigation to modify those rulings. For the background to the man himself, see George Pullman and the American palace car.
Britain's locked corridor
British railways adopted the idea warily. The Great Northern Railway introduced a gangway connection of American pattern in 1889. Then, in March 1892, the Great Western put into service a set of side-corridor coaches designed by William Dean, the first British train with a gangway between every carriage.
The sources disagree on details. Most give 7 March 1892 and the Paddington to Birkenhead service; some name Penzance, one gives 1 October 1892, and a local history dates the formation to 1891, perhaps the trial stage. Its make-up is better attested: a first, a second, a third and a brake third, all clerestory-roofed.
What is not in doubt is how the train was meant to work, and here the popular story of the corridor needs correcting. The gangways, offset to one side of the coach ends, were not there to let passengers roam. They allowed the guard to reach any compartment, and electric bells were fitted so that he could be summoned. Otherwise the connecting doors were locked. Passengers could use the side corridor within their own coach to reach the lavatory, and that was the extent of their freedom.
Even the arrival of food did not change the rule at once. When the Great Western introduced restaurant cars in 1896, they were gangwayed, but diners were expected to board the restaurant car at the start of the journey and stay there.
From novelty to national standard
Within a generation the locked door had become an open one, and the argument moved to which design to use: the British Standard type of the Great Western and the LMS, or the Pullman type of the LNER and the Southern.
- 1869 - LNWR royal saloons for Queen Victoria carry Britain's first flexible gangway.
- 1887 - Pullman secures the Sessions vestibule patents; the first vestibuled train runs on the Pennsylvania Limited.
- 1889 - The Great Northern Railway brings an American-pattern gangway to Britain.
- 1892 - The Great Western's Dean corridor train, gangwayed throughout, for the guard's use.
- 1896 - Great Western restaurant cars, gangwayed but not yet open for walking to.
- 1928 - The LNER's corridor tender lets crews change on the non-stop Flying Scotsman.
- 1948 onwards - British Railways standardises on the Pullman gangway for its Mark 1 coaches.
The corridor even reached the locomotive. For the non-stop Flying Scotsman of 1928, 392.7 miles from King's Cross to Edinburgh, the LNER built tenders with a side passage and a Pullman-type gangway, so a fresh crew could walk forward and take over at speed. British Railways later chose the Pullman connection for its Mark 1 coaches, specifically for its resistance to telescoping.
What the corridor made possible
The real consequence of the gangway was architectural. Once a train could be walked end to end, each carriage could specialise. A sleeping car could be all cabins along a side corridor, as in the European tradition shaped by Georges Nagelmackers, whose story is told in the European sleeping car. A dining car could be a restaurant rather than a refuge. A bar car could exist at all. Dressing for dinner and walking three carriages to the table is a direct product of the vestibule, as is the culture described in luxury train gastronomy.
There was a cost: a corridor coach carried fewer passengers than a compartment coach. Luxury, in railway terms, partly means paying for that corridor.
Walking the corridor today
The heritage trains still running are, almost without exception, gangwayed trains, and their layouts make the history legible. The restored 1920s and 1930s carriages of the British Pullman, departing from London, are Pullman cars in the literal sense, joined end to end so that the train works as one long dining room. The Venice Simplon-Orient-Express runs historic sleeping cars built around the side corridor, with a dining and bar section reached on foot from every cabin.
In Scotland, the Belmond Royal Scotsman ends in an observation car at the rear, a destination that only makes sense on a train you can walk through. Across Asia, the Eastern and Oriental Express follows the same grammar of cabins, dining car and lounge. For a wider survey of where these journeys run, browse our luxury trains.
Each time a passenger steps through the bellows between two carriages without a thought, they are doing something Queen Victoria declined to do and the Great Western's first corridor passengers were not permitted to.
