British Rail Classes 101 and 102

 

In 1955, British Rail published a Modernisation Plan to streamline the railway network, bringing it up to date in comparison to European standards. Steam power would be phased out in favour of diesel powered railcars and locomotives, and projects were put out to tender.^[6] BR hoped that by replacing steam with DMUs, costs would be reduced sufficiently to make rural lines viable.^[7]

Since there was no time for BR to issue a standard specification, train builders were invited to submit plans on the understanding that the units could be built and put into service quickly. Having gained experience with early lightweight DMUs, Metro Cammell won a contract and put the Class 101 into production. The type featured a steel chassis with an aluminium body to reduce weight. Five orders for batches were placed for the type.^{[8][failed verification]}

Metro-Cammell advertised their new train highlighting the wide availability and modern features the 101 offered. Demand was so high that at one point four cars per week were rolling off the Washwood Heath production lines.^[9] The trains underwent testing on the Sutton Park line near the works from 1956, before the sets were released to BR.^[10]

The 101s came in two, three or four car units, with two driving carriages one or two of which were powered by 11.3 litre BUT six cylinder diesel engines with epicyclic gearboxes. Being a first generation DMU, they were a prime example of a slam door train. They had a top speed of 70 mph (110 km/h).^[11]

The 101 DMU fleet was vast with 527 101s and 106 of the related Class 102s being built. The two types were distinguished by the type of engine fitted, but were eventually classified together as Class 101s only.^[12] In all, 760 individual vehicles were built in total, 465 were for the Eastern Region and North Eastern Region, 159 for the Scottish Region and 139 for the London Midland Region.^{[citation needed]}

In the mid-1970s, the type was chosen for a refurbishment to extend their service life. Vehicle interiors were improved with the fitting of fluorescent lighting, new upholstery and carpeting, and fitting of extra heating equipment. They also had uprated engines fitted.^[13] The work was carried out by BR Doncaster.^[14]

The Class 111 was a variant of the 101, having more powerful Rolls-Royce engines. They were built to serve Greater Manchester and West Yorkshire PTE. The 111 lasted in service until 1989, fourteen years earlier than the 101.^[15]

The 101 fleet was used across much of the British Rail network (with the notable exception of the Southern Region - apart from some inter-regional workings). Notable concentration of services included:

Class 101s operated various routes in Scotland starting in July 1958. Edinburgh - Dundee was a regular working, with units stabled at Dundee depot.^[16] Upon ScotRail's formation, the units continued in use and were in service up to Privatisation in 1997, with some painted in orange and black Strathclyde PTE livery.^{[citation needed]}

 

In January 1984, a fire at Ayr depot destroyed six 101s and as a result an equivalent number of Class 104 were drafted in to fill the gap.^{[citation needed]}

Upon Privatisation in 1997, ScotRail retained eleven units in service, running the Glasgow to Barrhead, East Kilbride, Paisley Canal and Whifflet as well as the Motherwell to Cumbernauld services. Although Class 101s were a common sight in Scotland up to the late 90s, they started to disappear from Glasgow Central high level with the introduction of the Class 156.^{[citation needed]} Newer Class 170s started a stock cascade and the type's withdrawal began. Upon the 101s final withdrawal from Scotland in November 1999, the remaining sets were returned to Manchester.^[17]

The type was seen in South Wales working commuter routed around the Valleys and West Wales Line until the early 1990s, and on rural Welsh lines until the early 2000s. In the 1970s, a diagram from Birmingham to Aberystwyth via the Cambrian Line was a regular route for the 101s.^[18] From 1982, they were used on the Central Wales Line between Shrewsbury and Swansea.^[19] The 101s were scheduled along with a mixture of other first generation DMUs and Sprinters to work the Crewe - Holyhead services from the early 1980s.^[20]

Starting on 14 April 1958, the region received a batch of two and three car units. Class 101s were extensively used for commuter services on the Cross-City Line and Chase Line in Birmingham and services to Worcester before being put to work in outlying areas.^[21]

Operating from Tyseley depot, the type was used all over the West Midlands well into the 1980s. Just as with the Class 116 which was also heavily used on the same routes, the 101s were withdrawn from WMPTE service on 12 July 1993 when the Cross-City Line was fully electrified. In all, the 101 served the West Midlands for over 35 years.^[22]

Arriving in 1957 at the newly opened Darlington depot, the 101s were initially used on runs between Darlington and Saltburn on the Tees Valley Line. Most of the first batch of 101s ordered were allocated to Darlington. The class continued to serve the line well into the 1980s.^[23] The type was withdrawn 21 September 1989 in favour of Pacers.^{[citation needed]}

 

The initial order of 339 vehicles were allocated to the Tyneside area. The 101s first went into service on 24 October 1956 when seven 4-car and 10 2-car units were delivered. A route from Newcastle to Middlesbrough followed. From February 1957, they began operating a stopping service between Newcastle and Carlisle. A longer diagram between Newcastle and Leeds offered a buffet service. The 101s routes were expanded to the whole Tyneside area, replacing the local steam-hauled services.^[24] This included the Alston line between Haltwhistle and Alston where the class operated until the line closed in 1976.

Later services were run by Tyne and Wear Passenger Transport Executive and stabled at South Gosforth depot. They remained in service in the region until 30 May 1981 when they were superseded by the Tyne and Wear Metro.^{[citation needed]} At which point, the class was withdrawn and the sets sent to Neville Hill depot in Leeds to be re-deployed.

 

An initial batch of 10 units went into service in Bradford in December 1956. Operating out of Neville Hill depot in Leeds, the 101s were used extensively for short commuter services. Because of the relatively underpowered engines, the more powerful Class 111 was paired up with some 101 units, while others were moved to other depots.^[25] Occasional services between York - Manchester and beyond were worked via the Calder Valley. Regular services were run between Leeds, Bradford, York and Sheffield but the units could also be seen in places such as Scarborough and Whitby.^[26]

 

From 1967, several 101 sets were transferred to serve the South West. Services from Reading to Gatwick Airport and Oxford to Paddington were common.^[27] Diagrams expanded as more 101s arrived in the region with regular runs in the Bristol area. They were stabled at Reading and Plymouth Laira depots, with the units serving until 1987 when they were largely replaced by Class 108s.^[25] Several 101s received Network Southeast branding and by the early 1990s had been scaled back to running local services between Didcot, Oxford and Bicester.^[28] However, some 101 units were still working in the Plymouth area as late as May 1993 with the final withdrawal coming in 1996.^[29]

Thanks to the withdrawal of other units and types, 101s were paired up with different carriages. From the early 1980s it was not uncommon for example for a 101 trailer to be paired to another first generation DMU driving car on various routes and different regions.^{[citation needed]}

First introduced in the region in January 1970, the 101 units were allocated to Norwich depot and used on rural lines, notably Norwich to Sheringham and on the Fen line, as well as regular services to Ipswich amongst others. In later years, additional units were based at Cambridge.^[30] The Cambridge-based trains primarily ran shuttle services from Cambridge to Royston and from Hitchin to Huntingdon.^[31] However, with the electrification of the region and introduction of newer rolling stock, by the early 1990s they had fallen out of favour and were re-allocated to other parts of the rail network.^[28] The remaining 101 unit was finally withdrawn from Norwich in August 1996.^[32]

When the Pacers serving Manchester to Blackpool shortly after their introduction proved unreliable in the mid-1980s, the 101 filled the gap at short notice despite not being common in the region.^{[citation needed]} The 101s were then rolled out across the Greater Manchester area.

Despite the intention to phase out the type and other Heritage DMUs in favour of newer stock, the 101 proved to be a dependable workhorse. Thirty five units were removed from service by 1992 and received a further refurbishment. At this point, they were repainted in Regional Railways livery, and had the class number applied concurrently with several Sprinter and Pacer sets. The work was once again undertaken at Doncaster.^[33] Along with other first generation types, corrosion of the body panels and asbestos used during construction was seen as major concerns and were leading causes for their eventual retirement.^[34]

Once the units from Scotland had returned, they were put into use working the rural lines around Greater Manchester, especially the Buxton and Hope Valley Lines on services into Manchester Picadilly.^[35] It was intended to phase the 101s out of service in favour of the Class 142 in the late 1990s, but the Privatisation of British Rail delayed those plans.^{[citation needed]}

 

Following privatisation the remaining 101 sets in mainline service fell under the ownership of Angel Trains and operated by the First North Western franchise once the units from Scotland had been returned to Manchester. FNW declined to repaint the trains again, and they retained their former liveries. A total of 18 sets were in service initially.^[36] Ongoing problems with the Pacer units and the Sprinters' use on other lines meant that the 101s were called on to continue in service. The 101s outlasted the Class 141 Pacer in service, a type which had been intended to replace the older unit.^[37]

The 101 was seen regularly running on the North Wales Coast Line service between Crewe and Holyhead alongside loco hauled trains as late as 1999.^[38] The type was unsuited to the route, and was replaced with the British Rail Class 175 from 2000.^[39] It fell to the 101s to run the stopping service from Manchester to Stoke-on-Trent, along with other rural routes in the north west.^[40]

Beginning in late 2000, the age of the units was starting to tell and the remaining 101s were gradually retired. They were used exclusively on the Hope Valley services until the end of their career. The very last scheduled service for the type anywhere was run on 24 December 2003 between Rose Hill and Manchester Piccadilly at which point the final five units were decommissioned from service, and sent to Shoeburyness for storage.^[41]

Because of the type's popularity and longevity in service, a final farewell tour for the 101s was run in late 2003 which was a railtour of northwest England.^[42]

• On 10 August 1961, Class 45 D105 running light to Neville Hill over-ran signals and collided with a Leeds - Scarborough Class 101 almost opposite Leeds East Signal Box. Leaking diesel caught fire and the leading two DMU vehicles (51440 & 59533) overturned, but were returned to traffic after repair. One person was killed, and two injured. The driver of the locomotive mistakenly accepted the signal that had been cleared for the DMU.^[43]
• On 15 June 1965, an empty stock train passed a colour light signal and two ground subsidiary signals at danger before colliding at slow speed with the leading coach of the approaching 15.57 Scarborough - Leeds Class 101. Both drivers and twelve passengers were injured.
• On 11 July 1967, A 101 working on the 10.11 Chester to Manchester Exchange service collided at a speed of approx. 20 mph with the rear of the 02.00 Margam to Carlisle Class 5 freight train which was standing at the Winwick Junction Down Fast Home signal. There were no injuries.^[44]
• On 16 February 1977, an express passenger train hauled by Class 55 locomotive 55 008 collided with a Class 101 diesel multiple unit operating an empty stock train after failing to stop at Darlington. One of the vehicles of the DMU overturned. The guard of the express was slightly injured. The cause of the accident was that the brakes on the carriages of the express had become isolated whilst the train was moving in a freak event. The train had struck an object on the track, which had caused a traction motor cover to come loose. This struck the handle of the brake isolating cock, closing it and thus separating the brakes between the locomotive and train.^[45]
• On 28 March 1983, the 20.58 Falkirk Grahamston to Glasgow Queen St. service collided with a van that was allowed to roll away and drop 40 feet into the cutting near Eastfield shed.

When TOPS was originally introduced only the Driving Motor Brake Second (DMBS) and the Driving Motor Composite (with Lavatory) (DMCL) were classified as Class 101 (AEC engines) or Class 102 (Leyland engines). The Driving Trailer Composite (with Lavatory) (DTCL) were either Class 144 or Class 147. The Trailer Seconds (with Lavatory) (TSL) were Class 162, the Trailer Brake Second (with Lavatory) (TBSL) were Class 168 and the Trailer Composite (with Lavatory) (TCL) were Class 171. Later all the cars were reclassified, becoming Class 101.

The Class 101 was one of the largest classes of first-generation DMUs and, partly thanks to their relatively late withdrawal from revenue-earning service, numerous vehicles have been preserved on heritage railways, including the Great Central Railway and the North Yorkshire Moors Railway. There are only three centre cars preserved: at the Severn Valley Railway, North Yorkshire Moors Railway and Mid-Norfolk Railway. No Trailer Brake Seconds were preserved.

Hornby Railways first produced a version of the BR Class 101 in OO gauge in 1958 which was last produced in 1977.^[48] Lima also produced a Class 101 for a number of years, in Green, Blue/Grey, Regional Railways and Network Southeast liveries. The tooling was used by Hornby following purchase of their assets. In 2007, Hornby reintroduced the Lima version of the OO gauge Class 101 in BR green and BR blue liveries.^[49] Bachmann Industries launched their BR Class 101 in OO gauge in 2014 and this has also been produced in a variety of liveries

The Class 101 DMUs were the basis for the character Daisy the Diesel Railcar in The Railway Series books written by the Rev. W. Awdry, and the adapted television series Thomas the Tank Engine and Friends, although Daisy is a single car.^[50][51][52] 101685 on the North Yorkshire Moors Railway is named after her.^[53]
