The Class 800 AT300 is a bi-mode multiple unit built by Hitachi for Great Western Railway and London North Eastern Railway. 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 were built by Hitachi between 2014 and 2018.

The trains were assembled at the Hitachi Newton Aycliffe facility from bodyshells shipped from Kasado, Japan.

As part of its production, the Class 800 is a part of the Intercity Express Programme (IEP) and is in the Hitachi AT300 product family. Their respective train operating company has also given the units separate brands; under Great Western Railway, they are known as Intercity Express Trains and under London North Eastern Railway, they are known as Azuma.
