British Rail Class 91

The British Rail Class 91 is a class of 140 mph, 6,300 hp electric locomotives ordered specifically for the East Coast Main Line modernisation and electrification programme of the late 1980s. Built to replace the previous Class 43 (better known as the InterCity 125), the Class 91s were given the auxiliary name of InterCity 225 to indicate their status as a new version of the 125 and their envisaged top speed of 225 km/h (140 mph). The other end of the InterCity 225 train set is formed of a Driving Van Trailer, built with a similar bodyshell to the Class 91 locomotives.
