[Also in Division G3] Apparatus for controlling the speed of a train comprises a tachometer generator 1 feeding a counter 2 which supplies an output pulse when a given number of tachometer output pulses have been counted, three storage counters 4, 5 and 6 with associated decoder circuits 7, 8, 9 and blocking control circuits 13, 17, 20 which are controlled via leads 14, 21, 22 energized by signals from the track, a programmer 10, connected to the decoders and also controlled by track signals via lead 24, which supplies a current representing the desired speed of the train to comparator 23, an integrator 25 fed from the tachometer which supplies an actual speed representation to the comparator and a brake relay 26 controlled by the comparator output. Constant speed.-Signals from the track via leads 14, 21, 22 block the decoder circuits, which then control the programmer to select a resistor combination which supplies the highest possible output current, simultaneously a signal from the track via lead 24 modifies the resistor combination so that the programmer supplies a current representative of the actual desired speed to the comparator 23. This current is compared with that representing actual speed supplied via integrator 25 and the comparison controls the braking relay 26. Controlled braking.-Assume a train has to reduce its speed to a low value at point B, Fig. 4, a track signal is applied at point A via lead 14 to unblock counter 4 and decoder 7. The decoder then controls the programmer 10 whereby each time counter 4 receives an input pulse from counter 2, i e each time the train has traversed a set distance, the resistor bank in the programmer is switched to reduce its output current by a fixed amount The output current of the programmer thus reduces linearly in steps and the train is controlled to follow the braking pattern 58. If now the train has also to be controlled to a predetermined speed at, say, point C on the track, a track signal can be supplied at position 67 to unblock counter 5 which proceeds to count the distance pulses but this action has no effect until a track signal is received, e.g. at point B to unblock decoder 8 when the train is then controlled to follow pattern 61.
