The British Rail Class 804 is a type of bi-mode multiple unit which will be built by Hitachi for East Midlands Railway. Based on the Hitachi A-train design, a total of 33 five-car units are to be built. Their intention is to replace the InterCity 125 and Class 222 trains currently operating on EMR's intercity routes.


In August 2019, East Midlands Railway placed an order for 33 five-car bi-mode units which will be deployed on services on the Midland Main Line replacing its High Speed Train, and Class 222 fleets. All are scheduled to be in service by December 2022.[2][3]

Hitachi have described the upcoming Class 804s as an evolution of the existing Class 802s with a revised nose profile, with facelifted end headlight clusters, giving the units a slightly different appearance. Additionally, there will be four diesel engines per five-carriage train (versus three on the 800s and 802s), and the carriages will be 2 metres (6.6 ft) shorter due to platform length constraints at London St Pancras.[4]
