Intercity Express Programme

The Intercity Express Programme (IEP) was an initiative of the Department for Transport (DfT) in the United Kingdom to procure new trains to replace the InterCity 125 and InterCity 225 fleets on the East Coast Main Line and Great Western Main Line. These new trains were designed and produced by Hitachi as part of their A-train family, classified as Class 800 electro-diesel units and Class 801 electric multiple units.
