Class 332

The Class 332 EMUs are used exclusively on the Heathrow Express out of London Paddington. The trains leave for the airport every 15 minutes on a journey which is non-stop and only takes 15 minutes.

Number built: 14 4 and 5 car sets
Built: 1997-98, 2002
Builder: CAF Siemens
Engine: 4 Siemens traction motors
Power: 1, 877 hp (1, 400 kW)

The EMUs were originally delivered as 3-car sets but have been reformed as 4 and 5 car sets. They were the first electric trains to operate on the Great Western Main Line after a portion was electrified as far as the airport junction.

Class 92

Designed for freight and overnight passenger traffic through the Channel Tunnel the Class 92 is an advanced and powerful 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 their planned work disappeared while they were 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
Engine: ABB 6FRA 7059B traction motors
Power: 6, 700 hp (5, 000 kW) - 25kV AC
5, 360 hp (4, 000 kW) - 750v DC

The Class 92 is a complicated locomotive with many systems duplicated to avoid the chance of failure in the Channel Tunnel. 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.
