The Coradia 1000 is a type of Diesel Multiple Unit (DMU) operating in Great Britain and which is part of the Alstom Coradia family of diesel and electric multiple units. There are two types that were built, the Class 175 and Class 180. [1]
As of 2023 [update] , only the Class 180 DMUs are in service and are operated by the train operating company Grand Central.
Both of the Coradia 1000 models utilise a diesel-hydraulic powertrain, with transmissions being supplied by German manufacturer Voith. [2] [3] The diesel engines were supplied by American manufacturer Cummins. [2] [3]
When both classes were new, they featured hydrodynamic retarders as part of their braking equipment. However, due to the unreliability of this equipment on both the Class 175 and Class 180, they were bypassed with the DMUs now just using their normal air brakes.
The Class 175 and Class 180 are capable of working in a multiple unit arrangement with each other, however they cannot work with other classes. [3]
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU.
A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control.
The British Rail Class 156 Super Sprinter is a diesel multiple unit passenger train. A total of 114 sets were built between 1987 and 1989 for British Rail by Metro-Cammell's Washwood Heath works. They were built to replace elderly first-generation DMUs and locomotive-hauled passenger trains.
The British Rail Class 158Express Sprinter is a diesel multiple unit (DMU) passenger train. It is a member of the Sprinter series of regional trains, produced as a replacement for British Rail's first generation of DMUs; of the other members, the Class 159 is almost identical to the Class 158, having been converted from Class 158 to Class 159 in two batches to operate express services from London Waterloo to the West of England.
The British Rail Class 175Coradia 1000 is a type of diesel multiple unit (DMU) passenger train from the Alstom Coradia 1000 family.
The British Rail Class 153 Super Sprinter are single-coach railcars converted from two-coach Class 155 diesel multiple units in the early 1990s. The class was intended for service on rural branch lines, either where passenger numbers do not justify longer trains or to boost the capacity on services with high passenger volume.
The British Rail Class 180 is a class of 14 diesel-hydraulic multiple unit passenger trains manufactured by Alstom at its Washwood Heath factory in 2000/01 for First Great Western (FGW). They are part of the Coradia 1000 family, along with the Class 175.
The British Rail Class 185 Desiro is a class of diesel-hydraulic multiple-unit (DHMU) passenger trains built by Siemens Transportation Systems in Germany for the train operating company First TransPennine Express. They are currently operated by TransPennine Express.
The British Rail Class 121 is a single-car double-ended diesel multiple unit. 16 driving motor vehicles were built from 1960, numbered 55020–55035. These were supplemented by ten single-ended trailer vehicles, numbered 56280–56289. They have a top speed of 70 mph (113 km/h), with slam-doors, and vacuum brakes. The driving motor vehicles were nicknamed "Bubble Cars" by some enthusiasts.
The British Rail Class 142 Pacer are diesel multiple-unit passenger trains built for British Rail (BR) from 1985 to 1987. They were built with a high level of commonality with the widely used Leyland National bus. They are part of the Pacer family of railbuses. The last set was withdrawn from service in 2020.
First North Western was a train operating company in England owned by FirstGroup that operated the North West Regional Railways franchise from March 1997 until December 2004.
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
The Alstom Coradia LINT is an articulated railcar of the Alstom Coradia family manufactured by Alstom since 1999, offered in diesel and hydrogen fuel models. The acronym LINT is short for the German "leichter innovativer Nahverkehrstriebwagen". It was designed by Linke-Hofmann-Busch and has been distributed as part of Alstom's Coradia family.
On the UK rail network, multiple working is where two or more traction units are coupled together in such a way that they are all under the control of one driver.
The Scharfenberg coupler is a commonly used type of fully automatic railway coupling.
The Alstom Coradia is a family of diesel multiple units, electric multiple units, and unpowered rail cars for intercity and regional service manufactured by Alstom, with variants operating in Europe, North America, and Africa.
A slam-door train or slammer is a set of diesel multiple units (DMUs) or electric multiple units (EMUs) that were designed before the introduction of automatic doors on railway carriages in the United Kingdom and other countries, which feature manually operated doors. The name came about because of the characteristic noise made by the passengers slamming the doors closed when the train was about to depart.
Diesel multiple units and railcars are trains, usually with passenger accommodation, that do not require a locomotive. Railcars can be single cars, while in multiple units cars are marshalled together with a driving position either end. As of December 2010, 23 percent of the rail passenger cars used on Network Rail are part of a diesel multiple unit.
The British Rail Class 600 Breeze was a proposed class of hydrogen fuel cell-powered multiple units that was to have been converted from existing BREL Class 321 electric multiple units. The project commenced in 2018, but was cancelled in 2022 before any conversions took place.
Transport for Wales Rail Limited, branded as Transport for Wales and TfW Rail, is a Welsh publicly owned train operating company, a subsidiary of Transport for Wales (TfW), a Welsh Government-owned company.
