Unable to proceed, Guard protect the train in rear.<\/p>\n<p>A train whistle is a device used to alert people and other trains to the presence of a train. It is typically sounded by the locomotive engineer, or loco pilot, to warn of the train&#8217;s approach. The whistle is also used to communicate with other train crews and to signal to the train&#8217;s crew when to start, stop, or slow down.<\/p>\n<p>The four short whistle sound is a standard signal used by train crews to indicate that the train is unable to proceed and that the guard should protect the train in the rear.
