Class 92

Designed for freight and overnight passenger traffic through the Channel Tunnel [1] the Class 92 is what is now known as a bi-mode electric locomotive that can operate on electricity drawn from both with 750v DC third rail and 25kV AC overhead lines. Unfortunately for the Class 92 a lot of it's planned work disappeared while it was being built meaning that many were stored out of use for a number of years, at one stage in the early 2000s over half the fleet was in storage. Nowadays more have been activated, some being exported to work in Europe. However the reliability of those that do remain in service on British rails has sometimes been questionable.

Number built: 46
Built: 1993-95
Builder: Brush Traction
Motor: ABB 6FRA 7059B traction motors (DC third rail & AC OHLE)
Power: 6, 700 hp (5, 000 kW) - 25kV AC
5, 360 hp (4, 000 kW) - 750v DC
Wheel arrangement: Co-Co

The Class 92 is a complicated locomotive with many systems duplicated to avoid the chance of failure in the Channel Tunnel [2]. Most of their work (of those not in storage or working in Europe) these days is on freight but some are also being used on Caledonian sleeper services from London to Scotland, however a number of failures have seen the introduction on these services delayed.

One interesting piece of trivia is that the very last train to be run on British Rail late on 21/11/1997 was hauled by 92 003.
