Transport for LondonC' stock
'C' stock
- Circle, Hammersmith & City Lines, District (Edgware Road-Wimbledon)
- Refurbished by RFS Industries, Doncaster, 1991-1994
These trains differed from the "A" stock as they were designed specifically for urban traffic and high passenger densities with short stops between stations and consequently considerable movement into and out of trains.
Among their new features was a secondary suspension system, thermostat controlled blower-heater fans mounted in the roofs and extra doors whose vestibules afforded an increase in standing space.
A subsequent order for more of the same produced a second batch, known as C77 stock. Comprising 67 cars for eleven trains with one car to replace a C69 unit which was destroyed in a bomb incident at West Ham in 1976.
These trains commenced operation on the District Line services between Edgware Road and Wimbledon in April 1978 - the short platforms over the western part of the Circle Line prevent the use of the longer District Line "D" stock cars.
This was the first manually controlled stock on London Underground to be fitted with rheostatic braking, using the traction motors for braking.
It was also the first to be equipped with a 'selective close' facility which allowed all the doors except one pair to be closed to retain interior heat whilst the trains were standing at terminal stations. They have four pairs of double doors on each side.
All trains were refurbished by RFS industries in Doncaster between 1991 and 1994. The seating was originally transverse except at the outer ends of the cars which were longitudinal, but upon refurbishment all seating is longitudinal throughout.
Although this kept the amount of seating the same, it did provide additional standing room in the gangways. Windows were introduced in the car ends that do not include driving cabs, to enhance personal security.
