British Rail Engineering Limited (BREL) was the railway systems engineering subsidiary of British Rail.

It was established on 1 January 1970 by the British Railways Board to operate its 14 rolling stock maintenance centres and to provide construction, maintenance, and repair services to Britain’s railways. A key activity of BREL was the manufacturing of new rolling stock, such as the InterCity 125 trainset, the Mark 3 carriage, and the British Rail Class 58 freight locomotive. Both domestic and international sales were pursued; rolling stock produced by BREL was exported to various nations, including the Republic of Ireland, Kenya, Taiwan, Sweden, Malaysia, Yugoslavia, and Bangladesh. Numerous projects were undertaken on a collaborative basis with private sector manufacturers, including Brush Traction, Metro-Cammell, and Metropolitan-Vickers. BREL also built numerous prototype rail vehicles, such as the Class 140 and Class 210 DEMUs and the experimental high-speed Advanced Passenger Train (APT) tilting train.

Throughout the 1980s, BREL was subjected to repeated restructuring and job cuts; various works, such as Ashford, Shildon, and Swindon were closed permanently. The organisation was effectively cut in two when the maintenance arm was split off as British Rail Maintenance Limited in 1987. The British government sought to make BREL more internationally competitive. The design and building of trains was privatised in 1989,[1] purchased by the Swiss-Swedish conglomerate Asea Brown Boveri (40%), Trafalgar House (40%), and a management-employee buy-out (20%). After ABB became the sole shareholder in September 1992, it was subsumed into ABB Transportation.

[train passing] ♪ background music ♪ (Narrator) Switches and crossings play an essential role in connecting the rail network. We use them to guide trains from one track to another and to enable lines to cross paths. Put simply, they're the junctions that allow us to create a multi-lined, multi-routed rail network. At Network Rail we own over 20,000 switch and crossing units. They come in many different shapes and sizes and all are made to measure for their specific location. To understand how switches and crossings work, we've first got to look at the wheel-rail interaction. Train wheels move along the rails guided only by the pound coin sized area of wheel that sits on the rail head. The wheel rim or flange doesn't normally touch the rail. Flanges are only a last resort, to prevent the wheels becoming derailed. A switch can guide a wheel in one of two directions. A crossing creates a gap in the rail for the flange to pass through. This is a switch. Also known as a point. It's the moving part of the switch and crossing layout and is made up of two long blades which can move across to guide the train one way or another. This is the switch rail. And this is called the toe. This is called the stock rail. It's a non-moving part of the switch. The two switch blades are fixed to each other by a stretcher bar to ensure that when one is against its stock rail the other is fully clear and provide room for the wheel flange to pass through cleanly. This is a crossing. It's the non-moving part of the switch and crossing layout that allows a train to pass in either direction once the switch has been set. This is the nose of the crossing. Either side of the crossing area, wing and check rails are provided to assist the guidance of the wheel sets through the crossing. Crossings can be either fabricated, made up of two machined rails joined together, or they can be cast as a single unit. Modern crossings are now cast from manganese steel which is an advanced alloy that gets harder with use. This is an important property, as the nose of the crossing can take high impact loads as train wheels pass through. (Lawrence) My name's Lawrence Wilton, and I'm a graduate engineer working for Network Rail. I'm here today to teach you about switches and crossings. The most simple form of S and C is the turn-out. This is a left-hand turn-out. As you can see, it diverges from the main route in a leftward direction. This is how it works. In normal mode, the left hand wheel rolls along the switch rail and there's flange way clearance for the right wheel to continue along the stock rail. The inside surface of the right flange is kept on course by the track rail. This restrains the wheel set and ensures it is directed along the correct route. Meanwhile, the left wheel transfers contact between the different parts of the crossing. That's where there's a high impact load. In the reverse the right wheel rolls over the switch rail and follows its geometry. The inside surface of the left flange is guided by the check, forcing it to follow the stock rail on the new route and the right hand wheel makes a crossing, again, impacting a load on the crossing nose. (Narrator) There are many different types of switch and crossing on the network. They include turn-outs, diamonds, cross-overs, and slip-diamonds. The type we use is determined by a number of factors including the number of lines involved, frequency of use and running line speed. Trains travelling at high speeds need long switches and crossings. At low speed, such as in stations, trains can make tighter turns. Train movements across the network are set and controlled by signallers who use switches to set routes for trains. Switches can be propelled by various devices. One of the simplest forms is a ground frame set-up. A series of rods and cams attached to levers in signal boxes. These are now largely being replaced by remotely operated hydraulic and electro-mechanical devices. (Lawrence) Seen by rail-sides all across the country, this is an HW2000 points machine. This is electro-mechanical. What we have here is your drive motor. To check that motor has done its job, over here we have an interlocking and detection system. Detection tells us when the points have completed their travel and locked. Locking holds the points in this state, so they cannot be physically moved. So when a train runs over the top, it remains in position. Facing point locks are one of the most important safety features on the S and C layout. They ensure that the points cannot be moved when set. This is important because failure to lock the switches could cause a derailment. (Narrator) As engineers, we face an ongoing challenge to maintain and improve our switch and crossing assets. Trains can create large impact and lateral forces as they change course. And these forces can cause wear and deformation. Switches and crossings therefore have a limited lifespan before we need to replace them. Less than 5% of track miles are made up of switches and crossings, but over 17% of our maintenance budget is spent on them. We'll continue to research and develop new inspection techniques and material usage to increase their performance. (Lawrence) It's all about creating a network that's safe, reliable and efficient. It's what we do.

History

Variant logo used on rolling stock and corporate sales
Later logo, circa 1991
The InterCity 125 was formed from Class 43 powercars built at Crewe Works and Mark 3 carriages built at Derby Litchurch Lane Works
Mark 2 carriages  were built by BREL's Derby Litchurch Lane Works

BREL was established by the British Railways Board on 1 January 1970 to take over the management of its 14 rolling stock maintenance centres, including Ashford, Crewe, Derby Litchurch Lane, Derby Locomotive, Doncaster, Eastleigh, Glasgow, Horwich, Shildon, Swindon, Wolverton, and York.[2][3] The principal object of BREL was the provision of a construction, maintenance, and repair services to Britain’s railways.[4][5]

A key activity of BREL was the manufacturing of new rolling stock for use by British Rail. Amongst those rail vehicles is the InterCity 125 trainset; produced between 1975 and 1982 and commonly referred to as the High Speed Train, was a diesel-powered high speed passenger train that travelled faster than any previous production British train.[6][7][8] In addition to production types, BREL built numerous prototypes, such as the Class 210 DEMU and the experimental high-speed Advanced Passenger Train (APT) tilting train.[9]

BREL did not have a monopoly on the manufacture of new rail vehicles; various private companies, such as Brush Traction, Metro-Cammell, and Metropolitan-Vickers amongst others, also manufactured rolling stock for British Rail, although in general, it was built to specifications produced by BREL. Furthermore, BREL often acted as a subcontractor to a main contractor, such as GEC, which supplied traction equipment. These contracts typically required BREL to build the frames, body shells, and bogies and install the traction and ancillary equipment of the primary contractor. The majority of the electric locomotive construction programmes of the 1980s, such as Classes 89, 90, and 91, was carried out in this manner. The Sprinter and Pacer families of diesel multiple-units (DMUs) were also manufactured with an emphasis on collaboration and competitive forces.[10][11]

In addition to the domestic market, BREL pursued international sales. The Mark 2 carriage proved to be attractive abroad, and derivatives were exported to the Republic of Ireland, Kenya, and Taiwan. BREL's entry to the Chinese market in the late 1980s was hoped to lead to expansive orders for as many as 1,500 carriages.[10] Freight wagons of various sorts were produced for overseas customers in Sweden, Malaysia, Yugoslavia, and Bangladesh. BREL was also a major supplier of components and general engineering equipment to numerous businesses that were not primarily involved in railways, such as the British Steel Corporation.[4] During the 1980s, BREL produced the British Rail Class 58 freight locomotive, which it had developed with the intention of attracting international orders.[12][13]

Throughout the 1980s, various sites operated by BREL were permanently closed, including Ashford Works in 1981, Shildon in 1984, and Swindon in 1986.[14][15] During 1987, Doncaster, Eastleigh, Glasgow, and Wolverton were transferred to the newly-created BR Maintenance.[4][16] The maintenance requirements of British Rail's rolling stock was reduced as newer vehicles, such as the Mark 3 carriages, were introduced that were designed to minimise operating costs; British Rail also progressively increased its use of electric traction which required less maintenance than diesel-powered trains, further reducing demand for BREL's services and leading to cuts in personnel employed by the organisation.[10][17] The loss of such jobs and the closure of certain sites became a politically charged matter during the late 1980s, which included threats of industrial action and allegations of insufficient investment.[10][18][19]

As early as 1986, the British government were examining operations to privatise BREL and make it more competitive on the international market.[10] Accordingly, amid the wider privatisation of British Rail during the 1990s, BREL was sold via a management buyout, with management and employees owning 20% and Asea Brown Boveri and Trafalgar House 40% each.[20][21][18] At the time of the management buyout, BREL's locations comprised Crewe, York, and two separate works in Derby; Derby Locomotive Works was closed in 1991.[22][4] In March 1992, ABB bought out the other shareholders, making BREL a wholly-owned subsidiary. It was subsumed into ABB Transportation in September 1992.[23][24][4]

The vast majority of BREL's output was rolling stock for British Rail, including Mark 2 and Mark 3 carriages, the latter for locomotive haulage and InterCity 125 diesel High-Speed Trains. BREL built the NIR 80 Class diesel-electric multiple units for Northern Ireland Railways. Other Mark 3 derived vehicles included Class 150 diesel multiple units in the 1980s and numerous electric multiple units such as Classes 313 and 317.

BREL had success in the export market, notably with Mark 2 and Mark 3 carriages for Iarnród Éireann and the Taiwan Railway EMU100 series.[25] Rolling stock was also manufactured for Ghana, Kenya, Malaysia, and Tanzania.[26][27][28][29]
