C stock is the mainstay of the services on the Inner Circle, running Circle Line trains and Hammersmith & City Line trains (Hammersmith to Whitechapel, and to Barking in peak hours). It also provides District Line services over the Edgware Road — Wimbledon section (the tunnels to Edgware Road (District) station cannot accept D-stock trains). Two batches of this type were produced, sometimes known as C69 and C77 stock, but these are identical for all purposes. Each train is made up of three two-car units, each of which has a Driving Motor and an Uncoupling Trailer; therefore, each train will have a cab facing outwards at each end, plus one cab facing a car-end-window one-third or two-thirds of the way down the train. The carriages are designed with the huge commuter peak flows in mind, having four sets of double doors on each side of every carriage.
The whole fleet has now undergone refurbishment, which has included the usual painting in LUL corporate livery and interior general re-fit, plus fitting of a Digital Voice Announcer (`Vera'), cutting of car-end windows to improve passenger confidence, transverse seating turned into longitudinal to create more standing-room, and yellow-painted grab-rails replacing the strap-hangers.
The TBC incorporates a deadman's handle, seen in the released position here. Unless the train is stopped or running at less than 7mph and the TBC is in the "Rheo 1 and hold" notch, the driver must not let go of the deadman handle or the emergency brakes will be applied (by exhausting the Westinghouse air brake pipe to the outside world). Note that this feature was not provided on earlier stocks (eg A stock, the driver having to move the selector (or in that case Reverser) key from "Forwards" to "off" every time he wanted to let go of the handle at a station.
The console-top has a sheet of perspex covering the speedometer, brake and reservoir pressure gauges and some warning indicators. On the edge of the console are door-operation buttons which are a comparatively recent addition: originally these trains had guards, and after that the door controls were behind the driver's seat (and are just visible on left). They were re-sited for comfort and convenience, probably during refurbishment. In front of the driver's tip-down seat can be seen the telephone handset by which he/she makes announcements and talks to the Line Controller by radio.
A closer view of the driving desk. A selector key can be seen in the selector barrel; various yellow notices appear under the perspex, together with a whistle-valve button which pokes through a hole in it. On the corner pillar are further controls, including a Rate Switch that allows the driver to select one of two rates of acceleration.
