 | | Class 253 and Class 254 were the classifications allocated to the production High Speed Train units. |
 | | The former class was used for Western Region sets, operating out of London Paddington, and the latter for Eastern Region sets, operating out of London King's Cross, since these regions used different formations - the Western Region [WR] used 2+7 sets, whilst the ER preferred 2+8 sets with a second buffet car. |
 | | In 2000, Class 255 was allocated for the reformation of certain HST power cars and trailers into semi-fixed formation trains, to be known as Virgin Challenger units, for use by Virgin Trains after the introduction of their new 'Voyager' trains (Classes 220 and 221). |
