A brake van, on a train, is a wagon at the rear of a goods train where a guard would sit with a hand brake. The job of this wagon was to provide extra braking force for a train and as an emergency hand brake, should an unfitted train become uncoupled from the locomotive and become a runaway train.
All brake vans served the same purpose: to supplement brake-force to a train. Brake vans are operated by the Guard, a member of staff on the train, who is in charge of making sure that the lights are in the correct place. This is because a signalman would need to see the tail-lamp to know that the train had not split, so that he can clear the line.[1]
Most vans had both normal brakes and vacuum brakes. They also contained a fire for the comfort of the Guard.
From the earliest days of railways in the Britain until 1890s, trains were rarely fitted with a continuous brake system for the entire train. Slowing and stopping trains relied on a brake on the locomotive, and brake vans and carriages, which had hand brakes that would slow and stop trains. This, combined with the coupling design of the era, buffer and chain coupling, which was prone to unexpected failure, resulted in many incidents of wagons and carriages rolling away uncontrolled. The Armagh rail disaster in 1889, where the rear portion of a passenger train ran away down a grade, colliding with a following train, killing 80, resulted in the Regulation of Railways Act 1889. This act, addressing key issues in the disaster, introduced minimum requirements for the brake systems on passenger trains.[3]
To provide for and use on all their trains carrying passengers continuous brakes complying with the following requirements, namely:
(i)The brake must be instantaneous in action, and capable of being applied by the engine-driver and guards; (ii)The brake must be self-applying in the event of any failure in the continuity of its action; [lower-alpha 1] (iii)The brake must be capable of being applied to every vehicle of the train, whether carrying passengers or not; (iv)The brake must be in regular use in daily working;
(v)The materials of the brake must be of a durable character, and easily maintained and kept in order.
However, the Regulation of Railways Act 1889 was only specific to passenger trains, and any carriages and wagons that may form a passenger train.[3] Freight trains, were still not required to have a continuous brake system, thus brake vans still remained a fixture on freight trains, and runaways still occurred. These trains, without continuous brakes, were referred to as "unfitted", reflecting the fact they were not fitted with a continuous brake.[4] By the mid-twentieth century, this would start to change as freight wagons with brakes began to appear on the railway, however the phase out of wagons not equipped continuous brakes took decades. As result, "partly fitted" trains, where only some of the wagons had continuous brakes, while others in the train did not, would be prevalent into the 1970s. However changes in freight traffic, freight wagon design and the demands of overall railway environment would see the near elimination of unfitted and partly fitted freight trains by the 1980s.
Pre-British Rail
This section needs expansion. You can help by adding to it. (November 2022)
Each railway produced its own design of brake van, and there was considerable variety. Generally, brake vans were kept within the owning railway, and when a goods train passed from one railway to another with the locomotive being changed at the exchange point, the brake van would be changed as well. From 1942, wartime conditions ended this practice, and brake vans were pooled; consequently, the Railway Clearing House designed a British Standard Brake Van, to be used by all the railways. Four were built by the LMS in 1943, which kept the first one for themselves and supplied one to each of the other three companies.[5] The GWR, LMS and SR did not adopt this, and continued with their own designs.[6]
Early British Rail
British Railways, being an amalgamation of four companies, that were in turn an amalgamation of 120 railways, merged only 24 years earlier, resulted in a wide variety of designs for brake vans. British Railways in the years immediately after its formation, continued to use the various wagon designs plans it had inherited, gradually adjusting designs, such as using steel in place of wood. In February 1948, the Railway Executive appointed the Ideal Stocks Committee to make recommendations on "ideal" wagon and locomotive designs for traffic of the 1950s. The committee also reviewed the matter of brakes on freight wagons. From an economic stand point, the committee identified that it would cost £31 million (equivalent to £49.24 million in 2021), and that the results of moving forward would land somewhere between an annual loss of £1.2 million (equivalent to £1.91 million in 2021) to an annual gain of £1.3 million (equivalent to £2.07 million in 2021) The committee ultimately recommended further investigation into if fitting of continuous brakes to all freight wagons should move forward.[7] In time, British Railways settled on a set design for new brake vans going forward, a 20 ton design, based on LNER's brake van design, with a few minor adjustments, to the length of the stepboards on the sides for boarding the brake van, and where hand rails were provided. These brake vans,
Taking advantage of the fact that brake vans were intended to and usually required at the rear of trains, including those used for 'permanent way' track work, a specials brake van was designed that carried a plough on each end, to assist in spreading track ballast as it was unloaded by ballast hoppers. The plough could be lowered using a wheel on the platform on either end. The vans, referred to as 'shark' brake vans, were based on the predecessor LMS' design, using the LMS brake van design.[8]
British Railways would go on to copy the LNER 'Toad D' brake van design,[9] which would become known as the 'British Rail Standard Brake Van'.
The 1963 The Reshaping of British Railways report would mark a shift in British Rail away from unfitted, wagonload, freight trains, and a desire to shift towards 'Liner Trains' (unit trains of shipping containers, and unit trains for freight, such as coal. This shift was motivated by the costs involved with the handling of wagonload trains, and the lack of profit in this sector of freight. There was a clear desire to move towards newer, brake equipped wagons, which would enable higher speeds, higher freight capacity, more wagons per train and would make more effective use of increasingly powerful locomotives.[10] A noted aspect of the proposed Liner Trains, were the new wagon would be intended for high speed operations, and outfitted with air or vacuum brakes.[11]
By the mid-1960s, wagonload freight was still unprofitable, incentivizing British Rail to curtail the service and in turn withdraw older, unfitted rolling stock.[12]
In 1968, the requirement for fully fitted freight trains to end with a guard's van was removed from the rule book, and the guard was allowed to ride in the rearmost locomotive cab, which provided a good view of the whole train. By this time, the Beeching Axe had reduced by two-thirds the amount of trackage in the UK; as a result, most steam locomotives had been withdrawn and most British Railways standard-design diesel and electric locomotives had double-ended cabs. Therefore, there was no operational need for so many brake vans, and many types were withdrawn.[13]
Later British Rail
In 1985, rail unions agreed to single-man operation of some freight trains, the first time trains did not have a guard on board for over 150 years. Further, the conclusion of almost all unfitted freight trains in the late 1980s, saw brake vans continue to become unneeded. At this point, brake vans were only required on select trains, often when demanded by railway regulations, typically dangerous goods, unusual cargos, and engineering trains[14]
The British Railways Working Manual for Rail Staff - Section 3 - Handling and Carriage of Dangerous Goods, known as 'Pink Pages', for the pink paper it was printed on, into the 1990s, required that trains carrying Class 2(c) Toxic gases, Hydrocyanic acid, nuclear flasks, along with any dangerous goods requiring an escort, must have a guard and brake van. Wagon labels for these specific cargos, used by British Rail to supplement standard dangerous goods placards and provide special instructions to train crews, contained the phrase "BRAKE VAN REQUIRED".[14]
The brake van was required to be either fitted with a brake matching the rest of the train, or have a brake pipe and brake gauge and emergency brake valve. The intended purpose of the brake van at the rear of the train was to enable the required protection of a train to be carried out, without staff walking past dangerous goods wagons.[14] The Pink Pages procedures for train crews following an accident involving toxic gases and Hydrocyanic acid contained clear warnings that "Driver and guard must never go towards each other past affected wagons."[14]
Dangerous goods trains requiring an escort had additional regulations, requiring that the escorts travel in the brake van, and that no more than 3 escorts could ride in the brake van with the guard, otherwise a second brake van for the escorts was required.[14]
Post privatization
In 2021, Preparation and working of freight trains - Issue 1, came into effect. This module of the railway rule book is the modern successor of the former Working Manual for Rail Staff documents Freight Train Operations or the 'White Pages' and Handling and Carriage of Dangerous Goods or the 'Pink Pages', now merged as a single document.[15][16] This revision removes all references to brake vans in the dangerous goods sections, with the related sections now instructing guards to either ride in the rearmost driving cab of a locomotive or an escort vehicle if one is provided. Brake vans are still mentioned in two sections directed at train preparers, regarding their inclusion in measuring the total length and weight of trains.[16]
In the years immediately prior to that, brake vans were only deemed necessary by HM Railway Inspectorate or Network Rail in certain special cases, for example in trains with unusual cargoes or track maintenance trains, or when one of the few single-cabbed locomotives was used, such as the British Rail Class 20. [citation needed]
Preservation and heritage railways
Brake vans are a common sight on many heritage railways such as the Helston Railway, the National Railway Museum or other small railways. On occasion, multiple brake vans will be coupled together in what is known as a "brake van special" for people to ride in on larger railways.
Design
A brake van 'ducket'.
Early brake vans were heavily weighted, adapted open freight wagons, equipped with an externally mounted hand-operated brake acting on all four wheels. The term 'brake van' began to be adopted from the 1870s onwards, when bespoke designed vehicles had a specific hut added to house the guard away from inclement weather. In keeping with tradition, most brake vans had an open area, but from the 1870s onwards this "veranda" became in part enclosed through the addition of a roof. Some vans became fully enclosed, but were equipped at each end with windows to allow the guard to view the entire train.
All of the operating equipment, specifically the brakes and sand boxes to improve traction, were located in the open area of the brake van. Brakes were normally controlled using a hand wheel mounted within the veranda, although some early designs continued with an externally mounted shaft. To improve the guard's visibility, many were fitted with look-outs on the roof, but side look-outs (termed "duckets") were the more common. The North Eastern Railway, Great Central Railway, London, Brighton and South Coast Railway and the Lancashire and Yorkshire Railway all built brake vans with a raised look-out at one end of the roof.
Two factors increase amount of friction between the brake van and the track; the number of wheels and the weight. In order to increase the weight brake vans often had a significant amount of ballast, in the form of concrete, cast iron or water tanks. Although most brake vans had two axles with four wheels, many railway brake vans had three axles and six wheels. The Great Northern Railway built a few eight-wheelers for very heavy coal trains which were the only rigid eight-wheeler brake vans built in the UK.[citation needed] In the 1930s, the London Midland and Scottish Railway (LMS) built three bespoke twin-bogied vans (four axles, eight wheels), for use on a particular branch line, where they replaced pairs of four-wheeled vans. The design covered the entire chassis length, with two extended verandas on either side of a cabin equipped with twin duckets.
To improve braking further, some LMS and LNER brake vans were fitted with vacuum brakes in addition to their normal brake, which could be operated by the guard. Almost all War Department brake vans were fitted with vacuum cylinders, as they were exclusively used on ammunition trains. The Southern Railway built 21 twin-bogie brake vans on redundant electric locomotive chassis, followed by 25 built on new chassis having carriage bogies, which were termed the "Queen Mary" brake vans. Designed for high speed operation on fully fitted goods trains rather than stopping power, they had a lengthened cabin, but did not cover the entire twin-bogie chassis.[17]
Other features of the van's interior would be a coal stove for the guard's heating and cooking needs, above which was a rail with hook on for the purpose of drying wet clothing. Furniture would consist of padded seating, with pads at shoulder height to protect the guard from the inevitable jolts and jerks ('snatches') of freight work, at the duckets; the guard would sit here for protection while the train was moving, unless absolutely necessary. He could reach the brake wheel from that position. This padded seat would be on top of a bench locker that stretched the entire side of one side of the van and half of the other (the side which the stove). A further padded seat was provided at the end of this bench locker where there was a small desk for the guard to perform whatever written work was necessary.
Equipment Carried
British Railways Rule 129 required the guard riding on any train to confirm his brake van carried the following equipment:
At least 2 "sprags":A section of wood designed to be shoved into gaps in the side of a railway wagon wheel, that physically prevent the wheel from rotating, effectively immobilizing a wagon. They were often used during shunting operations, or when wagons needed detached from a train as means to prevent runaways.[18][19]
A shunting pole: a wooden pole about 6 feet long with a twisted hook on the end which was used to couple and uncouple 3-link and instanter couplings without the guard having to position himself dangerously in between the vehicles,[18]
Various lamps: A guard would ensure they were carried, filled, trimmed, and ready for use where required by railway rules.[20][18]
Hand lamp: A lamp kept inside the brake van that was required to be lit: at night, during fog or falling snow, long tunnels, or any other location ordered by the Operating Superintendent,[18]
Tail lamp: A lamp mounted on the center of the brake van, that displayed a red light to anyone viewing the train from behind, such as a following train that there was a train, as enabling signallers to confirm the train was complete.[20][18]
Track circuit operating clips: A pair of metal spring clips connected by a wire used on lines with track circuits to indicate to the signalman that a train is occupying that section. They would be used in the event of an accident in which other running lines were fouled and trains on them had to be stopped as a matter of great urgency. The requirement to carry these arrived later on, as track circuits became more common. By 1986, a set of two track circuit operating clips was required to be carried in brake vans.[21]
Other equipment commonly found in the brake van, but not specifically required by Rule 129 included:
A brake stick: similar in shape to a square ended baseball bat; and used to lever down the handbrakes of wagons by placing it under the solebar and applying downward pressure,
Following the introduction of TOPS, a system used to track the movement of rolling stock across the British Rail network, all brake vans were allocated a TOPS code. Brake van codes always started with "CA" designating the vehicle as a 'brake van', with the final letter specifying what brakes the brake van was equipped with.
Brake vans that were reassigned to engineering use, were typically reissued a new TOPS code, starting with a "Z", as was standard for any engineering wagon of any type. The second letter, "T", indicated the vehicle was a brake van.
In addition to standard brake vans, a number of brake vans were used as the basis of a ballast spreading vehicle, fitted with a plough on each end that could be lowered, these vehicles were given "U".

The London, Midland and Scottish Railway (LMS) was a British railway company. It was formed on 1 January 1923 under the Railways Act 1921, which required the grouping of over 120 separate railways into four. The companies merged into the LMS included the London and North Western Railway, the Midland Railway, the Lancashire and Yorkshire Railway, several Scottish railway companies, and numerous other, smaller ventures.
A railroad car, railcar, railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck, also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport network. Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.
The Armagh rail disaster happened on 12 June 1889 near Armagh, County Armagh, in Ireland, when a crowded Sunday school excursion train had to negotiate a steep incline; the steam locomotive was unable to complete the climb and the train stalled. The train crew decided to divide the train and take forward the front portion, leaving the rear portion on the running line. The rear portion was inadequately braked and ran back down the gradient, colliding with a following train.
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by air brakes.
Brake van and guard's van are terms used mainly in the UK, Ireland, Australia and India for a railway vehicle equipped with a hand brake which can be applied by the guard. The equivalent North American term is caboose, but a British brake van and a caboose are very different in appearance, because the former usually has only four wheels, while the latter usually has bogies. German railways employed brakeman's cabins combined into other cars.
The British Rail Class 73 is a British electro-diesel locomotive. The type is unusual in that it can operate from the Southern Region's 650/750 V DC third-rail or an on-board diesel engine to allow it to operate on non-electrified routes. This makes it very versatile, although the diesel engine produces less power than is available from the third-rail supply so the locomotives are rarely operated outside of the former Southern Region of British Rail. It is one of the first bi-mode locomotives ever built. Following the withdrawal and scrapping of the more powerful Class 74 bi-mode locomotives in 1977, the Class 73 was unique on the British railway network until the introduction of the Class 88 bi-mode locomotives in 2017. Ten locomotives have been scrapped.
A number of different numbering and classification schemes have been used for carriages and wagons on Britain's railways, and this page explains the principal systems. Carriages and wagons have frequently had similar arrangements for classification and numbering, so are considered together. There are also links to other pages that deal in greater depth with the particulars of individual types.
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective on vehicles left without a prime mover. Clasp brakes are one type of brakes historically used on trains.
The London, Midland and Scottish Railway (LMS) Garratt was a class of Garratt 2-6-0+0-6-2 steam locomotive designed for heavy freight. A total of 33 were built from 1927, making them the most numerous class of Garratt in Britain.
The Charfield railway disaster was a fatal train crash which occurred on 13 October 1928 in the village of Charfield in the English county of Gloucestershire. The London, Midland and Scottish Railway (LMS) Leeds to Bristol night mail train failed to stop at the signals protecting the down refuge siding at Charfield railway station. The weather was misty, but there was not a sufficiently thick fog for the signalman at Charfield to employ fog signalmen. A freight train was in the process of being shunted from the down main line to the siding, and another train of empty goods wagons was passing through the station from the Bristol (up) direction.
A mineral wagon or coal truck is a small open-topped railway goods wagon used in the United Kingdom and elsewhere to carry coal, ores and other mine products.
Over the latter years of the 19th and early years of the 20th centuries, Penistone in Yorkshire gained a name as an accident black-spot on Britain's railway network; indeed, it could be said to hold the title of the worst accident black-spot in the country. The main line through the town was the Woodhead route of the Manchester, Sheffield and Lincolnshire Railway between Sheffield Victoria and Manchester, London Road. The line was heavily graded with a summit some 400 yards inside the eastern portal of the Woodhead tunnel.
The LNWR 1185 Class was a class of 0-8-2T steam tank locomotives designed by Charles Bowen-Cooke and introduced in 1911. They passed into LMS ownership in 1923 and 8 survived to British Railways ownership in 1948. British Railways numbers were 47875-47896.
As the Victorian Railways' fleet of Z vans began to age, the railways decided to invest in bogie designs for vans. Some van designs were included in a class of new passenger vehicles. Many other vans, for both freight and passenger work, were built separately from any other rolling stock developments, and these are the ones that feature here in detail.
The London and North Eastern Railway (LNER) inherited several styles of coaching stock from its constituents. Sir Nigel Gresley continued the styles that he had established pre-grouping at the Great Northern Railway (GNR) and for the East Coast Joint Stock.
The GWR Toad is a class of railway brake van, designed by and built for the Great Western Railway. Used by the GWR from 1894, and post-1947 by the Western Region of British Railways, its role was a safety brake on goods trains in the West of England, the Midlands and Wales.
The Great Central Railway (Nottingham) (formerly known as the Nottingham Heritage Railway) is a heritage railway located at the Nottingham Transport Heritage Centre (NTHC), on the south side of the village of Ruddington, in Nottinghamshire. The route consists of almost 10 miles (16 km) of the former Great Central Main Line from Loughborough South Junction (with the Midland Main Line) to Fifty Steps Bridge and the site of Ruddington's former GCR station, plus a branch line from Fifty Steps Bridge to Ruddington Fields station which is located on a former Ministry of Defence site next to Rushcliffe Country Park.
Buffers and chain couplers are the de facto International Union of Railways (UIC) standard railway coupling used in the EU and UK, and on some surviving former colonial railways, such as in South America and India, on older rolling stock. Buffers and chain couplers are an assembly of several devices: buffers, hooks and links, or turnbuckle screws.
The Victorian Railways used a variety of former traffic wagons around depots and for specific construction, maintenance and similar tasks. Very few of these vehicles were specially constructed from scratch, often instead recycling components or whole wagon bodies and frames from old vehicles that had been withdrawn from normal service as life-expired or superseded by a better design.
