Track apparatus actuating signals on trains and stopping trains. - Engines p r o v i d e d with the signalling - apparatus d e s c r i b e d in Specifications 12,008/07 and 98/08, are automatically checked or stopped on leaving a ramp at which a warning signal is indicated to the driver. The mechanically operated disclosing-shutter b carries a bracket a on which is pivoted a catch c having teeth d, e, normally held outwards by a spring f. The catch c is controlled by electro-magnets g, h so arranged in the engine circuit that one or the other is energized to attract the catch c whenever current is passing through the engine circuits from a ramp, that is, whenever the engine is receiving a ' line clear' signal. Opposite the catch is placed a lever i which actuates by means of a port k, a valve in the brake controlling system. Downward movement of the lever is limited by a sealed stop m, and both the lever and the catch are enclosed in a sealed box. When the engine arrives at a distant-signal ramp, the shutter b is lowered to a sufficient extent to place only the tooth e under the lever i, and if the engine passes off the ramp while no current is passing and a danger' signal is consequently being received, the raising of the shutter causes the tooth e to catch and turn the lever i to open partly the port k to a channel n, Fig. 1<a>, so as to cause the brake to be partly applied. Should a home signal be passed at 'danger,' the second tooth d, which in this case is drawn below the lever i by the shutter, turns the lever to open the port k fully to the channel n thereby putting the brakes on hard. If the signals passed are at ' line clear' the magnets g, h hold the catch c clear of the lever. The lever i, once actuated by the catch d, can only be replaced by removal of the sealed pin m. The shutter b also carries a spring catch p, which, on every downward movement of the shutter, actuates the lever of a bell or whistle q, which continues to sound until the driver returns it. Instead of controlling the brake valve, the catch c may be arranged to shut off steam, in which case a pneumatic cylinder operated by a similar air valve is preferably emp!oyed, and the piston is interlocked with the regulator handle so that the regulator shall close when the valve is operated and cannot be opened until the valve is replaced.
