The factory that controversially lost out on one of the UK's largest train orders is to build 30 new trains for use in East Anglia. Bombardier Transportation's Derby factory, the UK's last surviving train-building plant, is to build 30 four-car trains for the National Express East Anglia franchise, which runs services from London Liverpool Street. The new trains, built according to Bombardier's widely used Electrostar design, will cost £173m, provide extra capacity and allow older, 1980s-vintage units to be moved elsewhere.
