The British Rail Class 800 is a type of bi-mode multiple unit designed and produced by Hitachi for use in the United Kingdom on the Great Western and East Coast main lines. They use electric motors for traction, but in addition to operating on track with overhead electric wires, they have diesel generators to enable them to operate on unelectrified track. Based on the Hitachi A-train design, the trains have been built by Hitachi since 2014. They are very similar to the Class 802 units, which have uprated diesel engines and larger fuel tanks.

The units first entered service on the Great Western Main Line on 16 October 2017, under the brand name "Intercity Express Train (IET)" and the units entered service on the East Coast Main Line on 15 May 2019, under the brand name "Azuma."[8] The planned launch date had been December 2018, but this was put back when the trains were found to interfere with trackside signalling equipment.[9]

These trains are being assembled at the Hitachi Newton Aycliffe facility, alongside the related Class 801 electric multiple unit, from bodyshells shipped from the Kasado plant in Japan; no body construction takes place in the UK.[10]

The Class 800 units are part of the Intercity Express Programme (IEP) and are part of the Hitachi AT300 product family.[11][12] Train operating companies have also given the train separate brands. On Great Western Railway, they are known as Intercity Express Trains (IET) and on London North Eastern Railway, they are known as Azumas.[13]

Background and designEdit

Class 800/1 of LNER (left) next to a Class 43 of CrossCountry (right) at Leeds railway station. The Class 800 is to replace many class 43s.

As part of the UK Government's Intercity Express Programme (IEP), the Class 800 units are to be partial replacements for the ageing InterCity 125 trains which currently operate services on the Great Western Main Line and the East Coast Main Line. The Class 800s are bi-modal multiple units using electric traction motors able to draw power from electrified overhead lines where available or provide the electricity via underfloor diesel generators when outside the electrified network. The train specification requires that this changeover can occur at line speed. As part of the Great Western Main Line order was originally for Class 801s, all Great Western franchise units have the possibility to be converted to electric-only operation by removal of the diesel engines.[14]

The Class 800s are capable of driver only operation when necessary, but guards are to be kept on the units. Door release will be controlled by the drivers, with the guard being responsible for closing the doors using the control panels in the vestibule area. The driver will then carry out a secondary check of the side of the train before departure using the in-cab television monitors.[15]

Fleet detailsEdit

A total of 80 train sets will be constructed, with 36 five-car and 21 nine-car units intended for operation with Great Western Railway, plus 10 five-car and 13 nine-car with London North Eastern Railway.[7]

In March 2016, Virgin Trains East Coast announced that its trains would carry the brand name Azuma, the Japanese word for "East".[19] In June 2016, GWR announced that its trains would be known as Intercity Express Trains.[20] However, due to the early demise of Virgin Trains East Coast, they will not operate the new trains, which will enter service with successor London North Eastern Railway. Even so, the Azuma brand has been retained by LNER.[21]

In July 2016, it was revealed that GWR's intended fleet of Class 801 units were to be converted from pure EMU to bi-mode due to delays in the electrification. Subsequently, these were reclassified as Class 800/3.[18] The original 1.35 m3 (48 cu ft) fuel tanks will also be replaced with larger capacity 1.55 m3 (55 cu ft) tanks.

On 30 June 2016, GWR's test unit (800 004) ran from Reading to London Paddington carrying invited dignitaries.[22]

GWR unit 800 003 was named Queen Elizabeth II by the monarch herself, in a ceremony at Paddington station on 14 June 2017.[23] The Queen had arrived at Paddington on the unit, travelling from Slough on the 175th anniversary of the first ever train journey by a reigning monarch, made on the same route by Queen Victoria.[23] The name is carried in the form of a decal, rather than the more traditional cast metal plate; the name Queen Victoria is borne on the other end of the unit[24]

On 10 January 2018, unit 800 010 was named Michael Bond in a ceremony at Paddington by his daughter, Karen Jankel. This coincided with the 60th anniversary of the late author's famous Paddington Bear series of children's books, and the other end of the unit carries the bear's name.[25]

Introduction into serviceEdit

The Class 800 trains came into service on the Great Western Main Line on 16 October 2017.[26] Teething problems surfaced on the inaugural service, with the train running late and an air conditioning unit discharging water into a carriage.[27] Following further problems, the units were withdrawn from service for one day on 19 October, then re-entered service the next day.[28]

The units were due to enter service on the East Coast Main Line from December 2018[29][30][31] with London North Eastern Railway after Virgin Trains returned the East Coast franchise to the government, but the introduction has been delayed until 2019 owing to the units creating electro-magnetic emissions, in turn causing problems with signals and lineside equipment.[32] The 800s operated by LNER will keep the 'Azuma' branding Virgin had introduced for the class.


Despite being underfloor, the generator units (GU) have diesel engines of V12 formation. The Class 801 has one GU for a 5-9 car set. These provide emergency power for limited traction and auxiliaries if the power supply from the overhead line fails. The class 800/802 electro-diesel or Bi-Mode has 3 GU per five car set and 5 GU per nine car set. A 5 car set has a GU situated under vehicles 2/3/4 respectively and a 9 car set has a GU situated under vehicles 2/3/5/7/8 respectively.[1]

According to Modern Railways magazine, the limited space available for the GUs has made them prone to overheating. It claims that, on one day in summer 2018, "half the diagrammed units were out of action as engines shut down through overheating".[33]

The new interiors have received praise for the slightly increased leg-room and greater number of tables in Standard Class, compared to the Intercity 125 trains which they are to replace. However, the seats have been heavily criticised for excessive hardness and discomfort on lengthy journeys. They have also received severe criticism for a lower level of comfort for First Class passengers compared to the Intercity 125 trains, and the lack of a buffet counter or restaurant car facilities.[45] However, LNER sets will have buffet cars onboard the train.
