Designation for departmental locomotives From Wikipedia, the free encyclopedia
British Rail reserved the TOPS Class 97 designation for departmental locomotives, which were used for special or engineering duties. They were therefore of several different classes, lumped together for numbering purposes. Some locomotives were converted from redundant engines, whilst others were purpose built. In 2008, Network Rail once again used Class 97 for signalling test locomotives (Class 97/3).
Class 97 numbers were allocated in one of three ways:
Built by Ruston & Hornsby in January 1957 with the serial number 408493, this 4wDM shunter was ordered specifically for departmental use by the Signalling & Telecommunications department of the Western region at Reading Signal Works. The transmission was diesel mechanical, although the wheels were chain driven from the gearbox and the loco was rated at 88 bhp (66 kW) for a weight of only 17 tons. Tractive effort was a maximum of 9,500 lbf (42,000 N). Delivered to the WR with the number 20 it was renumbered to 97020 in May 1980. However withdrawal came in April 1981 and it was scrapped on site in August 1982 by Cartwrights of Tipton. For refuelling, it had to go via the main line to the depot at Reading.
This locomotive was a former Class 24 locomotive No.24061, which was taken over by the Railway Technical Centre, based at Derby, in 1975. It was initially numbered RDB 968007, and was given its Class 97 number in 1979. It was employed hauling various test-trains until retirement in 1988. It was painted in RTC's distinctive red/blue livery, and named "Experiment". After withdrawal it was preserved on the Midland Railway Centre having been to Vic Berrys at Leicester for Asbestos Removal then later the East Lancs Railway before a spell at the North Tyneside Steam Railway before later moving to the North Yorkshire Moors Railway.
This was former Class 25 locomotive 25131 used for training purposes at Toton depot. It had been withdrawn on 6 December 1982 and was reinstated as 97202 on 1 October 1983.[citation needed] It only lasted in Departmental service until January 1984 when it was again withdrawn, eventually being scrapped by Vic Berry.[1]
Subsequently, other training locomotives were numbered in the ADB 968xxx series.
These locomotives were converted from Class 31 locomotives. The first, no. 97203, was operated by the Railway Technical Centre, based at Derby. It was used to haul various test-trains operated by the centre. However, in 1987, the locomotive was written off after having sustained fire damage. Therefore, a replacement in the form of 97204 was converted. This later returned to normal traffic, as no. 31970. Both locomotives were painted in RTC's red/cream livery with a black bodyside band.
This was former Class 31 locomotive 31163, currently based at Chinnor & Princes Risborough Railway in Derby RTC livery.
Three former Class 25 locomotives were converted for use as mobile generators to provide electric heating on trains where the hauling locomotive could not supply this, including the Caledonian Sleeper. They were referred to as ETHEL units (Electric Train Heating Ex-Locomotives), and unofficially named Ethel 1, Ethel 2 and Ethel 3.[2] They were painted in a blue/grey livery in an effort to match the coaching stock livery of the day, but this was not too successful. All three have since been scrapped.
These locomotives have been refurbished from Class 37 locomotives at Barrow Hill Roundhouse by Network Rail and have been fitted with ERTMS signalling equipment. They are intended for use primarily on the Cambrian lines from Shrewsbury to Aberystwyth and Pwllheli, which requires an ERTMS-capable fleet. The locomotives were formerly 37100, 37170, 37178 and 37217 respectively.[3] A new inspection shed was built in 2008 at Coleham (Sutton Bridge Junction) in Shrewsbury for these locos.[citation needed]
On 2 September 2009, one of the locomotives (97303) hit a car on an unmanned level crossing near Penrhyndeudraeth, killing the car's driver.[4][5]
On 15 May 2024, 97304 was named Rheilffordd Talyllyn Railway at Tywyn by Peter Hendy, chairman of Network Rail. This was to commemorate 73 years of preservation of the Talyllyn Railway, and the close relationship between the commercial and preserved railways.[6][7]
97401 was a Class 46 'Peak' locomotive, bought by the Derby-based Railway Technical Centre straight from British Rail service in 1984. This locomotive did not receive its allocated departmental number and retained its original number of 46009. It was used in a high-publicity test, to prove the safety of rail transported nuclear flasks. The locomotive was deliberately crashed into a container at 100 mph (160 km/h). Whilst the locomotive was written off, the flask was undamaged.[8]
A second locomotive, no. 46023, was allocated the departmental number 97402. It was cannibalised for spare parts, to allow no. 46009 to reach the required 100 mph (160 km/h), since Class 46 locomotives are usually restricted to 90 mph (145 km/h).
These two locomotives were converted from Class 46 locomotives (97403 was 46035 and 97404 was 46045). They were operated by the Railway Technical Centre at Derby. 97403 was named "Ixion", and was used to evaluate wheelslip. It was painted in RTC's red/blue livery. 97404 was used as a source of spare parts. Both locomotives have been preserved.
These four locomotives were renumbered from Class 40 locomotives, which had all recently been withdrawn from normal traffic. In 1985, they were returned to use and employed on engineering trains around Crewe, and restricted to a maximum speed of 35 mph (56 km/h).[9] A major scheme was in progress to remodel the railways around Crewe railway station. After these duties finished, the four Class 40s continued in departmental service working ballast, freight and occasional parcels trains until finally being withdrawn in 1986/87.[9] However, three of the four were later preserved.
These five locomotives were renumbered from Class 45 'Peak' locomotives. They were used on infrastructure trains in association with major engineering works. All five locomotives were withdrawn by 1988, and have all since been scrapped.
These four locomotives were converted from Class 47 locomotives in 1989, and were used to haul test-trains throughout the country. Number 97561 was repainted in maroon livery and named "Midland Counties Railway" to commemorate the railway's 150th anniversary.
Three of the four locomotives were later renumbered into the range 47971–973, but continued to be employed hauling test-trains. They were later joined by 47974–976 and 47981. The fourth locomotive, no. 97472, was renumbered back to number 47472, and shortly after was withdrawn from traffic due to fire damage.
These shunting locomotives were purpose-built by Ruston & Hornsby at Lincoln in 1953 (97650) or 1959 (rest).
These battery locomotives were converted from the driving motor cars from former Class 501 electric multiple units, and usually worked in pairs.[11] They were modified by the removal of the seats, sealing of the doors and windows, and flattening of the roof.[11] The locomotives were able to work on third rail and by battery. They were powered by large batteries containing 160 cells, to work four 128 kW (172 hp) traction motors.[11] Two were based at Birkenhead North TMD and were employed around Birkenhead on the Merseyrail system (97701-702).[12] Others worked around North London and Glasgow.[11]
This number range was reserved for shunting locomotives converted from capital stock. Individual locomotives are described below.
This number range was reserved for Battery-Electric shunters on the Tyne and Wear Metro system.
Several Class 97 locomotives have been preserved on heritage railways.
