The British Rail Class 76, also known as Class EM1 (Electric Mixed-Traffic 1), [1] is a class of 1.5 kV DC, Bo+Bo electric locomotive designed for use on the now-closed Woodhead Line in northern England.
The prototype, LNER No. 6701, was completed at Doncaster Works in 1941 to a design by Sir Nigel Gresley, but electrification of the Woodhead Route, together with construction of 69 similar units, was delayed by the Second World War. It was tested on the few sections of 1500 V DC lines owned by the LNER, but had not worked any great distance by 1947 when it was loaned to Dutch Railways to help with their post-war shortage of locomotives. In September 1945, the LNER assigned it the classification EM1; previously, it had been unclassified. [1]
The prototype locomotive, renumbered 6000 in June 1946, remained on Dutch Railways until 1952 when the Woodhead electrification was complete. While in the Netherlands, it gained the name Tommy after the nickname given to British soldiers and ran for the rest of its working life with a nameplate, which included an explanation of the origin: "So named by drivers of the Netherlands State Railway to whom this locomotive was loaned 1947-1952." It was renumbered to 26000 following the formation of British Railways.
When new, the locomotive had Westinghouse air brakes and dual air and vacuum brakes were provided for the train. For operations in the Netherlands, the vacuum brake equipment was disconnected. When returned to Britain, the vacuum brake was restored but the air brake for the train was removed. [2]
26000 Tommy was used in everyday service, alongside the other EM1 locomotives equipped with train heating boilers. It was withdrawn in March 1970 and scrapped at Crewe two years later, [3] when passenger services were withdrawn over the Woodhead route and several locomotives became surplus to requirements.
The time in the Netherlands had shown that the design did not ride well at high speed, due to the bogie design. The buffers and couplings were mounted on the bogies which were then linked together by a drawbar, a feature intended to remove stress from the superstructure. It was also felt that the cabs were too small with poor visibility.
Between 1950 and 1953, a further 57 locomotives were built at Gorton locomotive works, Manchester, to a modified design; these were also classified EM1. [4] There were also to have been 24 built at Darlington Works, but these were cancelled. [1] Electrical equipment was supplied by Metropolitan-Vickers, who completed the final assembly of the locomotives at Dukinfield Works. They were later reclassified as Class 76, under the TOPS classification scheme introduced on 28 March 1968. [1]
The locomotives were fitted with twin diamond-shaped pantographs. At certain points on the Woodhead Line, notably in the vicinity of steam locomotive water-columns, the electric overhead lines were as high as 20 feet above the tracks. The pantographs had to stretch to almost their full height to reach the wires at some points, as BR practice utilised both raised in normal Woodhead operation in order to maximise current collection under any weather condition.
Although mainly intended for freight working, the locomotives also regularly worked Woodhead Line passenger services – especially after the sale of the Class 77 locomotives to the Netherlands Railways in 1968. Fourteen locomotives (26020, 26046–26057) were fitted with Bastian & Allen steam heating apparatus. Thirteen of these gained classical Greek names; these were removed in 1970, after the discontinuance of passenger services in January of that year.

The first section of the Manchester to Sheffield Woodhead route, between Dunford Bridge and Wath, was not electrified until 4 February 1952. The lines between London Liverpool Street and Shenfield had already been electrified in September 1949, using the same 1500 V DC system. On 27 October 1950, the first two locomotives to be completed, nos. 26001 and 26002, were sent to Ilford depot in Essex for trials; these were joined by 26003–26010 in early 1951. The trials involved a variety of trains, passenger and freight, including tests of the regenerative braking system on Brentwood bank, which has a gradient of 1:103 (0.97%). In June 1951, the ten locomotives were sent north to Wath, where the overhead lines had recently been energised, for further trials. [6] [7]
The locomotives were fitted with air brakes [2] and regenerative braking; the latter, which could only be used at speeds between 16 and 55 mph (26 and 89 km/h), caused current to be fed back into the wires during the long descents on both sides of the Woodhead Tunnel and so assisting any train which was ascending at the time. [8] Rheostatic braking was also fitted several years later as an additional safety precaution; this was effective below 20 mph (32 km/h). [8] Train brakes were operated by vacuum. [2] From November 1968, thirty of the locomotives were modified for multiple unit (M.U.) control. [9] This became particularly important from January 1970 with the introduction of Merry-Go-Round coal trains from South Yorkshire to Fiddlers Ferry power station near Widnes, operated by two Class 76s (and banked by two extra locomotives up the Worsborough incline between Wombwell and Silkstone). Such trains became the mainstay of the Woodhead Line in the 1970s. [10] Locomotives fitted with M.U. control were also given train air brakes; the last nine conversions had their train vacuum brakes removed at the same time. [9] A Clearcall intercom system was fitted, allowing communication between the drivers of the leading pair and the banking pair of locomotives via the overhead line. [11] An early version of this system had been tried on six of the locomotives in the late 1950s, but had been abandoned as unsatisfactory following tests concluding 26 May 1960. [2] Beyond the Woodhead Line, the trains to Fiddlers Ferry were diesel-hauled west of Manchester. [12]
As delivered, the locomotives were painted black. From the late 1950s onwards, Brunswick green was adopted, with small yellow warning panels on the cab ends. From the late 1960s and until withdrawal, the Class 76s started to appear in British Rail monastral blue with yellow cab ends.
The disposition of the Class 76 was inextricably tied to the fate of the Woodhead Line. The reduction of the freight traffic on the line, along with the ending of passenger services, resulted in the early withdrawal of several locomotives.
By the late 1970s, the locomotives were amongst the oldest in service and yet one of the most reliable classes, on account of robust design on British Rail; their replacement would ultimately become necessary. However, in July 1981, the closure of the Woodhead Line, between Hadfield in the west and Penistone in the east, resulted in the withdrawal of the entire fleet. The final service was operated in the early hours of 18 July 1981 by 76006 and 76014, hauling freight to Manchester. [13]
The class had served well, having been built to a sound design and well-maintained by the maintenance teams of Reddish and Wath. Most were still entirely serviceable when withdrawn.[ citation needed ] However, the Netherlands Railways were interested in their purchase for their heavy freight trains mainly from the North Sea Europoort inland, following a good service record of the prototype 6000 Tommy.
Controversy regarding the closure of the Woodhead Line, BR and government policies, plus BR's intention to avoid embarrassment regarding a sale for further use (thus discrediting their claims of expired working life from their traction policies, as had happened with the sale of the Class 77s) as well the greater age of the Class 76s compared with the Class 77s back in 1968, ultimately cancelled the sale.[ citation needed ] Accordingly, the remaining locomotives were scrapped, many at the yards of Booths of Rotherham, apart from a single preserved example now in the National Railway Museum in York.
One locomotive has been preserved by the National Railway Museum in York; no. 26020, later 76020, was specially chosen because it was built with stainless steel handrails and had been exhibited at the Festival of Britain. Later, it was the locomotive that pulled the opening day train through the Woodhead Tunnel. It retains the stainless steel handrails, although they are currently painted over.
One cab from another locomotive, 76039 Hector, which was formerly displayed at the Science and Industry Museum in Manchester, is now at the South Yorkshire Transport Museum in Aldwarke, Rotherham. [14]
A complete cabside and a driver's door from 76051 Mentor are preserved, in their original condition, at Barrow Hill Roundhouse, near Chesterfield.
Trix Twin Railway produced an H0 scale model of E26010 in black livery in 1959 and in green livery in 1960.
Heljan produces 00 scale models of E26051, in BR Green with half yellow panels, and 76014 in BR Blue.
Class 76 is being made as a kit and a ready-to-run model in OO gauge by Silver Fox Models. [15]
The InterCity 225 is an electric push-pull high speed train in the United Kingdom, comprising a Class 91 electric locomotive, nine Mark 4 coaches and a Driving Van Trailer (DVT). The Class 91 locomotives were built by British Rail Engineering Limited's Crewe Works as a spin-off from the Advanced Passenger Train project, which was abandoned during the 1980s, whilst the coaches and DVT were constructed by Metro-Cammell in Birmingham and Breda in Italy, again borrowing heavily from the Advanced Passenger Train. The trains were designed to operate at up to 140 mph (225 km/h) in regular service, but are limited to 125 mph (200 km/h) principally due to a lack of cab signalling and the limitations of the current overhead line equipment. They were introduced into service between 1989 and 1991 for intercity services on the East Coast Main Line (ECML) from London King's Cross to Leeds, York and Edinburgh.
The Woodhead line was a railway line linking Sheffield, Penistone and Manchester in the north of England. A key feature of the route is the passage under the high moorlands of the northern Peak District through the Woodhead Tunnels. The line was electrified in 1953 and closed between Hadfield and Penistone in 1981.
The Great Central Railway (GCR) Class 8K 2-8-0 is a class of steam locomotive designed for heavy freight. Introduced in 1911, and designed by John G. Robinson, 126 were built for the GCR prior to the First World War. Including wartime construction for the British Army ROD and the post-war GCR Class 8M, the class and its derivatives totalled 666 locomotives.
The British Rail Class 25, also known as the Sulzer Type 2, is a class of 327 diesel locomotives built between 1961 and 1967 for British Rail. They were numbered in two series, D5151–D5299 and D7500–D7677.
The British Rail Class 77, also known as Class EM2, is a class of 1.5 kV DC, Co-Co electric locomotive. They were built by Metropolitan-Vickers in 1953–1954 for use over the Woodhead Line between Manchester and Sheffield.
The Great Eastern Railway (GER) Class S69, also known as 1500 Class, and later classified B12 by the London and North Eastern Railway (LNER) is a class of 4-6-0 steam locomotive designed to haul express passenger trains from London Liverpool Street station along the Great Eastern Main Line. Originally they were designed by S. D. Holden, but were much rebuilt, resulting in several subclasses.
The GER Class L77, LNER Class N7, is a class of 0-6-2T steam locomotives. They were designed by Alfred John Hill of the Great Eastern Railway and introduced in 1915. The design was perpetuated by Nigel Gresley of the LNER after the 1923 grouping. 134 were built and one example is preserved.
The London and North Eastern Railway Class U1 was a solitary 2-8-0+0-8-2 Garratt locomotive designed for banking coal trains over the Worsborough Bank, a steeply graded line in South Yorkshire and part of the Woodhead Route. It was both the longest and the most powerful steam locomotive ever to run in Britain. It was built in 1925 with the motion at each end being based on an existing 2-8-0 design. The original number was 2395, and it was renumbered 9999 in March 1946, and then 69999 after nationalisation in 1948, although it retained its cab-side plate bearing its original number throughout its life. The locomotive ran for some time as an oil burner, and was tried out on the Lickey Incline in 1949–1950 and again, after the electrification of its home line, in 1955. These trials were unsuccessful, and so the locomotive was withdrawn in 1955 and scrapped.
The Manchester–Sheffield–Wath electric railway was an electrification scheme on British railways. The route featured long ascents on both sides of the Pennines with the long Woodhead Tunnel at its central summit close to the Woodhead pass. This led to the route being called the Woodhead Line.
The British Rail Class 306 was a fleet of electric multiple unit (EMU) trains introduced in 1949. It consisted of 92 three-car trains which were used on the Great Eastern Main Line between Shenfield and London Liverpool Street.
The British Rail Class 506 was a 3 carriage electric multiple unit (EMU) built for local services between Manchester, Glossop and Hadfield on the Woodhead Line, which was electrified in 1954 on the 1,500 V DC overhead system.
The LNER electric units were electric multiple units that ran on the Tyneside Electrics, a suburban system around the English city of Newcastle upon Tyne. In 1937 the London and North Eastern Railway (LNER) received articulated twin passenger electric units to replace the NER electric units that had been built in 1904–15 by the North Eastern Railway. The order including some single-unit motor parcel vans and motor luggage vans. In the 1960s declining passenger numbers and the high cost of renewing life-expired electric substation equipment across the system led to the replacement of the electric multiple units with diesel multiple units and the units were all withdrawn in 1967.
Hadfield railway station serves the Peak District town of Hadfield in Derbyshire, England. The station is one of the twin termini at the Derbyshire end of the Manchester-Glossop Line, the other being Glossop. It was opened by the Sheffield, Ashton-under-Lyne and Manchester Railway in 1844.
The Great Northern Railway (GNR) Class N2 is an 0-6-2T side tank steam locomotive designed by Nigel Gresley and introduced in 1920. Further batches were built by the London and North Eastern Railway from 1925. They had superheaters and piston valves driven by Stephenson valve gear.
The North Eastern Railway (NER) Class H, classified as Class Y7 by the London and North Eastern Railway (LNER) is a class of 0-4-0T steam locomotives designed for shunting.
The London and North Eastern Railway (LNER) Thompson Class L1 was a class of 2-6-4T steam locomotives designed by Edward Thompson. The prototype no. 9000 was built in 1945, but the remaining 99 were built under British Railways jurisdiction between 1948–1950. The prototype was well received, however the production batch were not, and all were withdrawn and scrapped between 1960 and 1962.
LNER Class Y11 was a class of three petrol powered 0-4-0 locomotives built by Motor Rail & Tram Car Company Limited under their Simplex brand and introduced in the years 1919–1925. Two were inherited by the London and North Eastern Railway (LNER) at its formation in January 1923, and a third was purchased later. Their British Railways numbers were 15097-15099. It was known as LNER Z6 before 1943.
The GER Class M15 was a class of 160 2-4-2T steam locomotives designed by Thomas William Worsdell and built for the Great Eastern Railway between 1884 and 1909. The original (F4) class of locomotives were fitted with Joy valve gear which was notoriously difficult to 'set'. This earned them the nickname of 'Gobblers' thanks to their high coal consumption rates. As a result, between 1911 and 1920, 32 of them were rebuilt by James Holden with Stephenson valve gear and higher pressure boilers. Despite this, the nickname stuck for many years after.
The GER Class Y65 was a class of twelve 2-4-2T steam locomotives designed by S. D. Holden and built by the company's Stratford Works in 1909–1910. They all passed to the London and North Eastern Railway at the 1923 grouping and received the classification F7.
Reddish Electric Depot was an electric traction depot located in Reddish, Stockport, England. It was situated on the west side of the Fallowfield Loop line between Hyde Road and Levenshulme South stations; however, neither of the Reddish stations were sited on this line. It was built to service the electric locomotives and local electric multiple units (EMUs) that were employed on the Woodhead Line between Manchester Piccadilly, Hadfield, Sheffield and Wath.
