Multiple Units Based On The Mark 3
The Mark 3 formed the basis of BR's Second Generation multiple unit fleet, which was progressively phased in from the early 1980s onward.
Electric multiple units include the 25 kV AC EMUs of the Class 317 and Class 318, and the 750 V DC EMUs of the Class 455 and Class 442. Also with a dual voltage EMU which is the Class319. Diesel multiple units include the short-lived diesel electric Class 210, and the diesel mechanical "Sprinters" of the Class 150. The cars for Classes 150, 210, 317, 318 and 455 units are built on 20 m frames, and are outwardly similar. However, those for Class 442 are on 23 m frames, and visually look very similar to the familiar HST mark 3 coach. The main visual difference being the use of swing plug automatic doors rather than the traditional "slam-door" as used on HST stock. The Class 153 and Class 155, while being of the "Sprinter family", are in fact built by British Leyland and have nothing to do with the Mk 3 carriage. This is also true of the Class 156, which was built by Metro-Cammell. The final batch of "Sprinters" of Class 158 (some rebuilt as Class 159), are of a design intermediate between that of the Mk 3 and the later Mk 4. In addition, a fleet of nine 450 Class DMUs were built at Derby for Northern Ireland Railways using Mark 3 bodyshells and Mark 1 underframes, together with refurbished power units and traction motors, recovered from the former UTA 70 class units. The last EMUs built that are based on the Mark 3 carriage are the Class 321 and 322 units.

Famous quotes containing the words multiple, units, based and/or mark:
“... the generation of the 20s was truly secular in that it still knew its theology and its varieties of religious experience. We are post-secular, inventing new faiths, without any sense of organizing truths. The truths we accept are so multiple that honesty becomes little more than a strategy by which you manage your tendencies toward duplicity.”
—Ann Douglas (b. 1942)
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbours household, and, underneath, anothersecret and passionate and intensewhich is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (18731947)
“Few white citizens are acquainted with blacks other than those projected by the media and the socalled educational system, which is nothing more than a system of rewards and punishments based upon ones ability to pledge loyalty oaths to Anglo culture. The media and the educational system are the prime sources of racism in the United States.”
—Ishmael Reed (b. 1938)
“There is a close tie of affection between sovereigns and their subjects; and as chaste wives should have no eyes but for their husbands, so faithful liegemen should keep their regards at home and not look after foreign crowns. For my part I like not for my sheep to wear a strangers mark nor to dance after a foreigners whistle.”
—Elizabeth I (15331603)
