Abstract
When the emergency valve 1 (necessary for manual release from the exterior of the pneumatic safety latches P of railway carriage access doors, especially for high and very high speeds) is not in a position such as to render operative the safety mechanism built into the system, an acoustic indicating device 21 with a function of an alarm is activated by the fact that it is supplied with compressed air from the control line. The said acoustic indicating device 21 is however disabled when the emergency valve is in the correct position for activation of the built-in safety mechanism. (Fig. 2). <IMAGE>
