Design
The fleet of 46 locomotives was built by a consortium of Brush Traction and ABB Traction. Parts construction was sub-contracted, with final construction and commissioning being undertaken at Brush's erecting shops at Loughborough between 1993 and 1996 (First unit was produced from 1992, and was finished in April 1993).
The bodyshells, shared with the Class 60 diesel locomotives but with a modified front end, were fabricated by Procor (UK) of Horbury and delivered pre-painted in the then-standard triple grey livery. Propulsion is provided by two ABB traction converters using GTO devices, with control via an ABB MICAS-S2. Maximum power is 5 MW (6,700 hp) on 25 kV or 4 MW (5,400 hp) on 750 V; with a tractive effort of 360 kN.
The locomotive is fitted with both rheostatic and regenerative braking, in addition to standard westinghouse air brake equipment. An electrical train bus is fitted to enable two locomotives to work in multiple formation, either double-heading or push-pull train with a Driving Van Trailer or DBSO.
To eliminate the possibility of locomotive failure in the Channel Tunnel, most of the electrical systems are duplicated.

Famous quotes containing the word design:
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
—Sidney Buchman (1902–1975)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“You can make as good a design out of an American turkey as a Japanese out of his native stork.”
—For the State of Illinois, U.S. public relief program (1935-1943)
