First Great Western Class 180 DMU 2 sets coupled together at London Paddington Station. All Class 180 DMU’s were pulled from service by the end of 2007 and returned to their leasing company with less than 6 years of operation due to reliability problems. They were replaced by refubished 30 year old HST train sets retired by other operators. I personally think this is a awesome shot, showing off the curved livery of the trains.

The InterCity 125 was the brand name of British Rail's High Speed Train (HST) fleet. The InterCity 125 train is made up of two power cars, one at each end of a fixed formation of carriages, and is capable of 125 mph (201 km/h) in regular service. Initially the sets were classified as Classes 253 and 254. A modified variant of the power cars operates in Australia as part of the XPT train.

The Class 390 Pendolino is a type of train used in Great Britain. They are electric multiple units using Fiat's tilting train pendolino technology and built by Fiat Ferroviaria. Fifty-three 9-car units were built for Virgin Trains from 2001 to 2004 for operation on the West Coast Main Line (WCML). The trains were the last to be assembled at Alstom's Washwood Heath plant, in Birmingham, before its closure in 2005.

Shunting signals allow a train to move forward onto a line which may already be occupied. Shunting signals may be attached to a main signal in which case they are only illuminated when the shunting movement is required (known as a subsidiary signal), and they display two white lights at an angle of 45 degrees. The driver may pass the signal with caution at a speed which allows the train to stop short of any obstruction.

The British Rail Class 43 is the TOPS classification used for the InterCity 125 High Speed Train power cars, built by BREL from 1976 to 1982. The class is the fastest diesel unit in the world, with an absolute maximum of 148 mph (238 km/h), and 125 mph (201 km/h) regular service speed, although there are claims that this diesel rail speed record has been broken twice unofficially: by Russian (168 mph, 1992) and Spanish (159 mph, 2002-07-09) trains.
