British Rail Class 91 electric locomotive 91110
Photographed at Grantham station, southbound, on 6 February 2009.
From 1994-1998 this locomotive, originally numbered 91010, was named "Northern Rock", from 2001 onwards named "David Livingstone".
This class of 140 mph, 6,300 hp locomotives was ordered for the East Coast Main Line as InterCity 225 trains, referring to their top speed of 225 km/h (140 mph). The other end of each train has a Driving Van Trailer (82XXX numbering).
The fleet was built in two batches, the first 10, then the remaining 21, between 1988 and 1991 at BREL, Crewe under subcontract from GEC to work with Mark 4 coaches. At the time the Class 91s were branded by British Rail as the 'Electra'.
The asymmetric body style is streamlined at one end to allow high speed operation with the fixed sets of Mark 4 coaches in push-pull operation. An additional requirement of the design was that they could operate as normal locomotives. This led to a second cab being incorporated into the 'flat end'.
The fleet underwent a refit between 2000 and 2003 to improve reliability, which resulted in the renumbering of the fleet from 910XX to 911XX.
