The
Class 800 Super Express is a type of
electro-diesel train to be used in the United Kingdom, based on the
Hitachi A-train design. They are to be built by
Hitachi from 2015. The first units will be delivered for the
Great Western Main Line (GWML), beginning service there in July 2017 and on the
East Coast Main Line (ECML) from 2018. These trains will be built at
Hitachi's purpose-built facility at Newton Aycliffe, alongside the related
electric multiple unit Class 801.

Intercity Express Programme
As part of the UK Government's
Intercity Express Programme, the Class 800 units are to be partial replacements for the aging
InterCity 125 trains which currently operate services on the
Great Western Main Line and the
East Coast Main Line. The Class 800 units will be
electro-diesel multiple units, able to draw power from
electrified overhead lines where available and power themselves via underfloor diesel generators outside the
electrified network. The train specification requires that this changeover can occur at line speed. The trains can be converted to electric-only operation by removal of the diesel engines. [...]
