The British Rail Class 22 or "Baby Warship" was a class of diesel-hydraulic locomotives designed for the Western Region of British Railways and built by the North British Locomotive Company. They were very similar in appearance to the Class 21 diesel-electrics, although shorter in length by almost five feet. The nickname Baby Warship related to the similarity in appearance (and internal equipment) to the British Rail Class D20/2 or Class 41 Warship Class. The Class 22s were numbered D6300-D6357. [8]

D6300 was introduced to traffic in 1959 and deliveries continued until 1962. The Class 22s were allocated to Bristol Bath Road, Laira Plymouth, Newton Abbot and Old Oak Common. The majority of the class always operated in the West of England, on a range of local passenger and freight work, with smaller numbers of the later units operating on local work in the Bristol area and around London Paddington (notably moving empty carriages between the main station and Old Oak Common yard).
Initially the locomotives had some problems with engine and transmission faults, but could be returned to North British Locomotive Works (NBL) for repair under the contractual agreement. By 1961, reliability had improved, but with the more powerful locomotives of Classes 35, 42, and 43 now being available, the locomotives were displaced onto more secondary duties, including work on the former Southern Region lines west of Exeter. By the mid 1960s, the locos had settled down to give reliable service, with availability over 85%. [10] [note 1]
NBL went bankrupt in 1962 and, by the late 1960s, withdrawn locomotives were being used to provide spares. Attrition was inevitable and the withdrawals, which had commenced in 1967, finished with the withdrawal of 6333, 6336, 6338 and 6339 on 1 January 1972. Ex-London Midland Region Class 25 diesel-electrics were drafted in as replacements.
The NBL type 2s were introduced in all-over green livery with a light grey skirt band, mid-grey roof, red buffer beams and black underframe. Numbers appeared below all four cab windows and the BR 'lion and wheel' emblem was placed high on the bodyside as centrally as possible. Later a small yellow warning was added. From 1967 some locos were repainted in the new corporate rail blue livery. The first four repaints, D6300, D6303, D6314 and D6327 had small yellow warning panels which they retained until withdrawal, later blue repaints had full yellow ends. Only about half the class were repainted into blue. The BR logo was placed immediately below each cab window, with the loco number below this; on some locos this was reversed.
Dapol released a 00 gauge model of the class 22 in late 2011. [11] [12]
D0280 Falcon was a single prototype diesel-electric locomotive, built for British Railways in 1961. It was one of a series of three prototypes: Falcon, DP2 and Lion, eventually leading to the Class 47 and Class 50. A requirement was expressed by the BTC at a meeting on 15 January 1960 for new Type 4 designs of Co-Co arrangement, which would be lighter than the earlier 1Co-Co1 locomotives such as the Peak classes, produced under the Pilot Scheme.
The British Rail Class 52 is a class of 74 Type 4 diesel-hydraulic locomotives built for the Western Region of British Railways between 1961 and 1964. All were given two-word names, the first word being "Western" and thus the type became known as Westerns. They were also known as Wizzos and Thousands. The final Class 52 locomotives were withdrawn from service in 1977.
The British Rail Class 14 is a type of small diesel-hydraulic locomotive built in the mid-1960s. Twenty-six of these 0-6-0 locomotives were ordered in January 1963, to be built at British Railways' Swindon Works. The anticipated work for this class was trip working movements between local yards and short-distance freight trains. The good all-around visibility from the cab and dual controls also made them capable of being used for shunting duties. The order was expanded from 26 to 56 in mid-1963, before work had started on the first order. They were numbered D9500-D9555.
The British Rail Class 15 diesel locomotives, also known as the BTH Type 1, were designed by British Thomson-Houston, and built by the Yorkshire Engine Company and the Clayton Equipment Company, between 1957 and 1961. They were numbered D8200-D8243.
The British Rail Class 108 diesel multiple units were built by BR Derby from 1958 to 1961, with a final production quantity of 333 vehicles.
The British Rail Class 24 diesel locomotives, originally known as the Sulzer Type 2, were built from 1958 to 1961. One hundred and fifty-one were built at Derby, Crewe and Darlington, the first twenty of them as part of the British Railways 1955 Modernisation Plan. This class was used as the basis for the development of the Class 25 locomotives.
The British Rail Class 26 diesel locomotives, also known as the BRCW Type 2, were built by the Birmingham Railway Carriage and Wagon Company (BRCW) at Smethwick in 1958–59. Forty seven examples were built, and the last were withdrawn from service in 1994. Like their higher-powered sisters, the BRCW Classes 27 and 33, they had all-steel bodies and cab ends with fibreglass cab roofs. They were numbered D5300-D5346.
The British Rail Class 122 diesel mechanical multiple units were built by Gloucester RC&W in 1958. Twenty single-car, double-ended driving motor vehicles, nicknamed "Bubble Cars", were built, numbered 55000–55019. These were supplemented by nine single-ended trailer vehicles, numbered 56291–56299.
D0260, named Lion, was a prototype Type 4 mainline diesel-electric locomotive built in 1962 by a consortium of Birmingham Railway Carriage and Wagon Company, Sulzer the engine maker and Associated Electrical Industries, at BRCW's Smethwick works near Birmingham.
DP2, meaning Development Prototype number 2, was a prototype Type 4 mainline diesel locomotive, built by English Electric in 1962. DP2 was effectively the prototype for the later Class 50; it trialled the engine and electronic systems later used in that class of locomotives.
The British Rail Class 41 diesel-hydraulic locomotives were built by the North British Locomotive Company in Glasgow during 1957 and 1958. Although they were withdrawn before TOPS was introduced, British Rail classified them as Class 41. All were named after Royal Navy vessels, hence the nameplates each bore a subtitle "Warship Class".
The British Rail Class 43 diesel-hydraulic locomotives were built by the North British Locomotive Company (NBL) from 1960 to 1962. They were numbered D833–D865.
The British Rail Class 20, otherwise known as an English Electric Type 1, is a class of diesel-electric locomotive. In total, 228 locomotives in the class were built by English Electric between 1957 and 1968, the large number being in part because of the failure of other early designs in the same power range to provide reliable locomotives.
The British Rail Class 17 was a class of 117 Bo-Bo diesel-electric locomotives built 1962–1965 by Clayton Equipment Company and their sub-contractor Beyer, Peacock & Co., on behalf of British Railways (BR).
The British Rail Class 42 Warship diesel-hydraulic locomotives were introduced in 1958. It was apparent at that time that the largest centre of expertise on diesel-hydraulic locomotives was in West Germany. The Western Region of British Railways negotiated a licence with German manufacturers to scale down the German Federal Railway's "V200" design to suit the smaller loading gauge of the British network, and to allow British manufacturers to construct the new locomotives. The resultant design bears a close resemblance, both cosmetically and in the engineering employed, to the original V200 design. Warship locomotives were divided into two batches: those built at BR's Swindon works were numbered in the series D800-D832 and D866-D870, had a maximum tractive effort of 52,400 pounds-force (233,000 N) and eventually became British Rail Class 42. 33 others, D833–D865, were constructed by the North British Locomotive Company and became British Rail Class 43. They were allocated to Bristol Bath Road, Plymouth Laira, Newton Abbot and Old Oak Common.
The British Rail Class 35 is a class of mixed-traffic B-B diesel locomotive with hydraulic transmission. Because of their Mekydro-design hydraulic transmission units, the locomotives became known as the Hymeks. They were numbered D7000-D7100.
The British Rail Class 21 was a type of Type 2 diesel-electric locomotive built by the North British Locomotive Company in Glasgow for British Rail in 1958–1960. They were numbered D6100-D6157. Thirty-eight of the locomotives were withdrawn by August 1968; the rest were rebuilt with bigger engines to become Class 29, although those locos only lasted until 1971.
The British Rail Class 23 were a class of ten Bo-Bo diesel-electric locomotives built by the English Electric Company (EE) in 1959. The power unit used was a Napier Deltic T9-29 9-cylinder engine of 1,100 bhp (820 kW) driving an EE generator, which powered the four traction motors. They were numbered from D5900 to D5909.
The British Rail Classes 105 and 106 diesel multiple units were built by Cravens Ltd. of Sheffield from 1956 to 1959. The class were built with a side profile identical to British Railways Mark 1 carriage stock, using the same doors and windows. None were selected for refurbishment. The last passenger car was withdrawn from service in 1988.
The British Rail Class 29 were a class of 20 diesel-electric Bo-Bo locomotives produced by the re-engining of the NBL Type 2 units. The units were designed for both passenger and freight trains.
