Real-Life History

The British Rail High Speed Train, widely known as the InterCity 125, revolutionised rail travel in Britain when it entered passenger service in 1976.

Its distinctive streamlined Class 43 diesel-electric power cars were built at British Rail Engineering Limited's Crewe Works between 1975 and 1982, while the air-conditioned Mark 3 passenger coaches were built at Derby.

Powered by a Class 43 at each end, the HST could travel at 125 mph in regular service, dramatically improving journey times and passenger comfort.

The trains became particularly famous on the Great Western Main Line, connecting London Paddington with Bristol, South Wales and the West Country.

Over the decades, HSTs underwent major upgrades, including replacement diesel engines, refurbished interiors and modernised equipment.

Under Great Western Railway, the fleet adopted the operator's distinctive dark-green livery. As newer Intercity Express Trains replaced the full-length HST formations, shorter four-coach sets, known as the Castle Class, continued serving regional routes through the South West and South Wales.

After almost five decades, the InterCity 125 remains one of Britain's most recognisable and influential passenger trains.
