A Class 158 in original British Rail pre-privatisation Express livery

British Rail Class 158 Express Sprinter is a diesel multiple-unit (DMU) train, built for British Rail between 1989 and 1992 by BREL at its Derby Works. They were built to replace many locomotive-hauled passenger trains, and allowed cascading of existing Sprinter units to replace elderly 'heritage' DMUs.[1] Class 159 trains are almost identical to Class 158s, having been converted from Class 158 to Class 159 in two batches.[2][3]

Description[]

Variants[]

Template:Unreferenced section A total of 182 units were built. The majority were built as two-car sets. 17 units were built as three-car units; eight of these units have since had the centre car removed, while another eight have been upgraded to be Class 159s.[2] The final ten units were built specifically for West Yorkshire PTE Metro services around Leeds.

There were three varieties of unit when built. The standard batch, two- and three-car units (158701—158814 and 158901—158910) had Template:Convert/hp Cummins engines. The next batch (158815—158862) were built as non-standard to enable Template:Convert/hp Perkins engines to be fitted. The final batch (158863—158872) were given higher-powered Cummins engines of Template:Convert/hp, as it was originally intended that these units would work the steeply graded Welsh Marches Line. Another 22 of these higher-powered units were built, and became three-car Class 159 trains. Over time, the units have become mixed up as franchises changed, and higher- and lower-powered units can be seen working on the same routes. All units use P4-4A and T4-4A bogies.

Passenger facilities and performance[]

When introduced, British Rail described the Class 158 as bringing "new standards of comfort and quality to rail travel on Regional Railways' key long-distance cross-country routes".[4]

As built, interiors were described as fully carpeted, with "panoramic" windows and a variety of seats arranged both airline-style and in bays of four around tables. Unlike previous members of the Sprinter family, such as the Class 156 SuperSprinter, the Class 158 featured air conditioning, an on-board payphone, power-operated interior doors, a toilet in each carriage, and provision for a refreshment trolley service. Despite an increased top speed of Template:Convert/LoffAoffDbSoff, the train also promised a smoother, quieter ride than its predecessors.[4]

Class 158 trains were expected to achieve 13,500 miles of operation between major services and a range of up to 1,600 miles from each refuelling.[4]

Technical problems[]

Despite the attention given to passenger facilities, the phrase "garden shed engineering" has been used to describe the build and technology of the Class 158.[5] As a lightweight unit and the first members of the Sprinter family to use disc brakes, autumn leaf mulch built up on wheel rims and prevented the trains from correctly operating signalling track circuits.[6] Though later solved by installing scrubbing blocks to clean the wheels, temporary solutions were sought in October 1992, with some units split and formed into hybrid units with Class 156 coaches,[7] as the latter had tread brakes which cleaned the wheels as a by-product of their operation.

The class has also suffered from unreliable air-conditioning systems[5] since the outlawing of the CFC gases with which they were originally designed to work.[8] Following privatisation, many operators undertook to re-engineer or entirely replace such equipment.[9] As a result, the systems in use and their effectiveness now vary across the fleet.

The lightweight aluminium body of the Class 158 leads to a good 'route availability' score,[10] meaning that it is able to operate in parts of Britain where heavier units cannot. However, the trains were once blocked from operating between Manchester and Buxton due to the possibility of the large roof-mounted air vents striking low bridges[citation needed] and have also been refused permission by Network Rail to operate on the Conwy Valley and Borderlands lines due to station dwell times and issues of platform clearance.[11][12]

Operations[]

British Rail[]

ScotRail was the first part of British Rail to introduce the Class 158 to service, gaining a fleet of 46 units which entered squadron service in 1989. These were employed on Glasgow Queen Street to Edinburgh Waverley services, as well as services to Aberdeen and Inverness. The Class 158 then went on to be deployed elsewhere in Britain, primarily in the Midlands, northern England and Wales.[4]

With the majority of the fleet coming under the control of the Regional Railways division, the train became a mainstay of secondary express services between provincial towns and cities. Examples included long-distance trans-Pennine services in the north of England, as well as a range of upgraded regional services under the Alphaline brand in the Midlands and Wales.

A small batch of units numbered 158747-158751 were used by InterCity to supplement its core fleet on some cross-country services, mainly from the North West to Scotland, but also to Portsmouth. Units regularly appeared on off-peak workings between Birmingham and Manchester, and also on Sunday mornings between Birmingham and Doncaster.

Post privatisation[]

After the privatisation of British Rail, the Class 158 fleet was divided among several franchises. There is an ongoing fleet shuffle with many units being swapped between operators.[citation needed]

ScotRail[]

The first privatised incarnation of ScotRail inherited a 46-strong fleet which continued in service. Following the introduction of newly built Class 170 units on primary express services in 1999, the Class 158 fleet was reduced in number by six, with those remaining cascaded away to secondary routes such as the Far North Line. This in turn allowed older trains in the company's fleet to be withdrawn.[citation needed] However, First ScotRail and Northern Rail operate the largest fleet of Class 158 units.

In 2003, plans existed for part of the fleet to be swapped with Class 156 units operated by Central Trains, as the latter were thought better suited to some of the short-distance routes now being operated by ScotRail's 158s.[13] However, this failed to materialise and by the mid-2000s operations of the ScotRail 158s ranged from short hops (such as Glasgow Queen Street to Anniesland) to rural lines and long-distance expresses, supplementing other express units. In 2010 these units started to appear at Glasgow Central station to run on the Glasgow Central to Edinburgh via Shotts line, and on to the Glasgow Central to Whifflet line. Some additional units have since been acquired from other operators to provide extra capacity.[14][15]

Refurbishment and reliverying has also taken place since privatisation. The original ScotRail franchise applied its own livery to trains, followed by a further repaint by First Group after it took control of the franchise. The fleet has now gained a permanent blue-and-white livery based on the Scottish Saltire, after Transport Scotland announced in September 2008 that it was specifying a permanent livery for all Scottish trains, which will not be changed in the event of a change of franchisee.[16] Interiors have also seen attention on more than one occasion. The most recent refurbishment of 25 units involved repainting, new seating, extra luggage space and new customer information systems.[17][18][19] Toilet retention tanks were also fitted.

Several of the ScotRail units have had names attached - for example 158702 is named "BBC Scotland - 75 Years", 158707 is named "Far North Line - 125th Anniversary", 158715 is named "Haymarket" and 158720 is named "Inverness and Nairn Railway - 150 Years".

Arriva Trains Wales[]

File:Barmouth railway station MMB 06 158823.jpg

Arriva Trains Wales (ATW) 158823 departs Barmouth with a service from Pwllheli to Birmingham International. Class 158 Express Sprinter trains are required on Cambrian Line services as they are the only ATW trains fitted with the ERTMS signalling used there.

In the early days of privatisation, Class 158 Express Sprinter trains were in regular use by Wales and West to supplement its Class 175 Coradia fleet on its long-distance Alphaline services from south Wales to north-west England, north Wales, Cornwall and London Waterloo, as well as on some Central Trains services to Cardiff Central and along the Cambrian Line.[20] Successor companies Wales and Borders Trains (2001) and Arriva Trains Wales (2003) continued to use this type of train on similar workings, with a total allocation of 40 trains also allowing Cambrian Line services to become entirely Class 158-operated.[21] By the end of 2006, a total of 16 trains (158815-158817 and 158842-158854) had returned to the leasing company[22] as Arriva gained exclusive use of the entire Class 175 Coradia fleet which had previously been shared with other train operators.

The remaining 24-strong Class 158 Express Sprinter fleet became permanently based at a purpose-built depot in Machynlleth during 2007.[23] Despite initial problems in retro-fitting the necessary 'glass cockpit'-style driver controls,[24] Arriva's Class 158 Express Sprinter trains became the first fleet in the UK to be equipped for regular use with the ERTMS signalling system.[25][26] Accordingly, the units operate all Cambrian Line services between Mid Wales and Birmingham, as well as supplementing the Class 175 Coradia trains on other long-distance routes.[27] In 2009, Arriva also proposed using the fleet to provide direct service between Aberystwyth and London,[28] although this proposal was later rejected by the Office of Rail Regulation.[29]

A complete refurbishment programme to provide the trains with an 'as new' interiors took place between December 2010[30][31] and October 2012. Funded by the Welsh Assembly Government at a cost of £7.5m, work completed includes interior and exterior repainting, along with replacement of seating, wall coverings, carpets, lighting, luggage racks and toilet fittings. A passenger information system has been fitted, while selected seats have gained at-seat power sockets for mobile phones and laptops.[32] Until this refurbishment, the fleet had seen only minor attention to its interior since a refit by Wales and West in the late 1990s, as well as having been only partially repainted into Arriva colours externally.[22]

East Midlands Trains[]

Class 158 Express Sprinter trains were introduced to the East Midlands by Regional Railways Central to replace the Class 156 SuperSprinter on long-distance express services branded as Alphaline, such as Norwich to Liverpool Lime Street via Nottingham. Following privatisation, Central Trains operated these services but quickly procured a large fleet of Class 170 Turbostar trains for such services and transferred the Class 158 fleet to secondary routes such as Birmingham New Street to Hereford and Derby to Matlock.[citation needed]

East Midlands Trains (EMT) has a fleet of 25 trains inherited from Central Trains, with some units transferred from First Great Western and South West Trains. EMT's Class 158 Express Sprinter trains operate long-distance express services (such as Norwich to Liverpool)[33] and secondary non-express workings such as Nottingham to Skegness, Nottingham to Matlock and Leicester to Lincoln Central.

The hourly Norwich to Liverpool service has been criticised for overcrowding,[34] especially between Liverpool and Nottingham. This resulted from the Department for Transport specifying two-coach trains in the EMT franchise starting in November 2007. In the light of persistent and excessive overcrowding, with some passengers being left behind on occasions, the DfT eventually admitted that it had made a mistake.[33] Various cascades of other trains enabled more Class 158 stock to be released for this route, and from the December 2011 timetable change the busiest services have been lengthened to four-coach trains between Liverpool and Nottingham, with units splitting and joining at Nottingham as necessary, two-coach trains being regarded as adequate between Nottingham and Norwich. Further services on this route will be strengthened from December 2012.[33]

Great Western Railway[]

The Wales and West franchise (later Wessex Trains) originally operated twelve Class 158 Express Sprinter trains on long-distance services on the Wessex Main Line. These trains were extended into three-coach formations with the acquisition of further units. Unlike the purpose-built three-car Class 158 and Class 159 trains, the centre car was a Driving Motor with the cab locked out of use and an adapter to connect the different-sized gangways.[citation needed]

In 2006, First Great Western (FGW) inherited the Wessex Trains fleet following the merger of the Great Western and Wessex franchises. FGW then swapped most of their former Wessex Trains Class 158s for former Transpennine Express;[35] examples. This was so that FGW could have all Class 158 trains that were owned by Porterbrook.[citation needed] During late 2007 and early 2008, the FGW Class 158 Express Sprinter fleet was refurbished. Improvements included: re-upholstery of seats, and repainting or replacement of interior fittings, alterations to interior lighting and total replacement of toilets. Additionally the windows have been replaced with safer laminated glass and Halon fire extinguishers replaced with foam ones. At the same time the trains' engines were overhauled and the trains repainted in FGW's own lilac and blue colours.[36]

The fleet is now used on the long-distance Cardiff Central to Portsmouth Harbour/Brighton, and Weymouth to Worcester Shrub Hill/Great Malvern services.[citation needed] Great Western Railway operates a total of 19 trains, 4 of which being hybrids (units formerly 2 cars but lengthened to 3 cars with a driving cab in the middle coach) one is a purpose built 3 car set and the remaining 14 are 2 car sets.

Northern/Transpennine[]

Following privatisation Northern Spirit (later renamed Arriva Trains Northern, and subsequently Northern Rail in 2004) was created from Regional Railways North East. Northern Spirit inherited a large fleet of Class 158 units, many of which were used on TransPennine Express services, the rest on West Yorkshire Metro-sponsored services. First North Western (descended from Regional Railways North West) had eight Class 158 trains, which were based at Newton Heath and used on various mid- to long-distance routes, which were transferred to Leeds Neville Hill depot at the start of the Northern Rail franchise and are now exclusively used on former Arriva Trains Northern routes. A number of 158s are currently sponsored by Merseytravel despite the fact that they do not go near Merseyside. This sponsorship is to ensure that Class 156s were cascaded from West Yorkshire to the busiest Merseyside services.[citation needed]

In late 2004, TransPennine Express obtained further units from Central Trains, allowing the formation of six 3-car units, 158971-976.[citation needed]

In 2006 First TransPennine Express started to replace its Class 158 trains with newer Class 185 Pennine and Class 170 Turbostar trains.[citation needed]

Virgin CrossCountry also operated a small number of Class 158 trains, numbers 158747-158751, before the introduction of the Class 220/221 Virgin Voyagers. These were used on Manchester Piccadilly/Liverpool Lime Street to Glasgow Central/Edinburgh Waverley services via the West Coast Main Line as well as services through the Stroud Valley between Swindon and Birmingham New Street. Most of these units are now operated by First Great Western.[citation needed]

Northern Rail has recently completed a refurbishment programme on the three-car Class 158 DMUs and is continuing to refurbish its fleet of two-car Class 158 DMUs.[citation needed] It and First ScotRail operate the largest fleet of Class 158 units.

South West Trains[]

Currently South West Trains operates Class 158s from Salisbury to Waterloo and on the Salisbury to Romsey via Southampton Central service, between Brockenhurst and Lymington on weekdays, and on a variety of local journeys within Hampshire.[2] Should South West Trains receive a three-car train, it will be integrated into a Class 159 unit, possibly to avoid confusion. One unit is on a daily loan contract to First Great Western, whilst South West Trains Class 158s have also been hired out to sister Stagecoach company, East Midlands Trains. South West Trains operates Class 158s 158880-890. Originally brought in to replace South West Trains class 170 fleet, SWT's class 158s saw a brief use on the former Reading to Brighton service, before the service was truncated at both ends within the new South Western franchise of 2007 (This service now runs with a 450 from Basingstoke to Havant).

Virgin Trains[]

Prior to the introduction of the Class 220/221 Virgin Voyagers, Virgin Cross Country operated a small number of Class 158 units, numbers 158747-158751. These were used on Manchester Piccadilly/Liverpool Lime Street to Glasgow/Edinburgh services via the West Coast Main Line. One also did the Swindon-Stroud-Birmingham route. Most of these units are now operated by First Great Western.[citation needed]

In 1990-91, BREL built twelve 3-car units based on the Class 158 for State Railway of Thailand.[37][38] These differ from the British units in being fitted to Thailand's metre gauge, featuring differently styled outer-end gangways, manually operated inward-opening hinged doors (as opposed to the British plug doors), and additional air-conditioning. They originally retained the original white, blue and black 'Regional Railways Express' livery.[38] All units of Class 158 of State Railway of Thailand were refurbished in 2011.[39]
