Description
24 two-car units were built as direct replacements for the elderly Class 416 2EPB units which operated on the Central Division of the Southern Region of British Rail. Units were delivered into traffic painted in Network SouthEast blue, red and white livery. Units were numbered in the range 456001-024. Each unit consisted of two carriages; a driving motor and a driving trailer. The technical description of the unit formation is DMSO+DTSO. Individual carriage numbers were as follows:
- 64735-64758 - DMSO
- 78250-78273 - DTSO
When first introduced, the units suffered from many technical and reliability problems, which delayed the replacement of the 2EPB units. However, once they settled down the units were used on many services, including London Bridge to London Victoria via Crystal Palace, and London Victoria to Horsham. Before the lines closed in 1997 to allow the building of Tramlink, Class 456 units worked services on the West Croydon to Wimbledon Line. Recently, more Class 456 EMU trains have recently been allocated to Victoria - Epsom via Sutton and West Croydon, especially at peak times, as well as services from Epsom Downs and Dorking.

Famous quotes containing the word description:
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
