All power cars were withdrawn by 1989, the last unpowered car went in 2000.
Three vehicles saw early withdrawal. DMBS NE50285 went first in November 1966 due to accident damage. It was noted in April the following year at the back of Bradford Hammerton Street shed, without engines, transmission, windows or interior fittings, and its rear sheeted over to cover accident damage. TSL 59103 was withdrawn during the week ending September 6th, 1969. The third was DMBS E51547, withdrawn during the week ending July 25th, 1970.
The buffet cars were phased out early. 59575 was the first to go in July 1973 (entering preservation), then 59573/6 went in September 1975. The remainder (59574/7/8) spent time away from the last of the class based on the ScR before withdrawn in November 1981.
The four first batch power cars went in 1987, three going into non-passenger use. Their trailers were withdrawn one each in 1986/7/8 and one (56091/54091) surviving into 2000 working in Regional Railways set 101658. This is pictured in Manchester Piccadilly on October 13, 1994, the power car is 51175. Ian Buck.
For the second batch 50285 had been withdrawn in 1966 as already mentioned. The next power car to go was DMC 50270 in 1982 leaving an equal number of DMBS/DMC vehicles to converted to single engine cars. These were withdrawn in 1986 (1 pair), 1987 (3 pairs) and 1989 (5 pairs). One TSL had been withdrawn in 1968, another in 1979, the main withdrawals were between 1985 and 1995.
Similar to the batch two power cars, one batch three power car had been lost early (DMBS 51547) and a corresponding vehicle withdrawn at the time of the single engine conversions - DMC 51560 in 1982. The conversions went in 1986 (1 pair), 1987 (4 pairs) and 1989 (4 pairs). The TSL vehicles went one each in 1986/88/89/93.
