Even for "fogging" mechanical devices have been invented to replace human agency. One of these, called a "torpedo machine," is used on the Manhattan Elevated Railway, New York. It has a magazine of five torpedoes; and is connected to the signal levers in such a way that, on the signals being set to danger, a torpedo is placed in a position to be exploded by the first passing wheel. On the signal being returned to "clear," the torpedo, if unused, is replaced in the magazine; but if used, the next torpedo of the series takes its place. Though detonators cost but a few pence a dozen, so many have to be used in a prolonged fog that a single company sometimes expends three or four thousand pounds annually on them in addition to several more thousands required to pay for the labour of laying them in position. In course of time the detonator will no doubt be replaced by mechanical methods of direct communication between signalman and driver. Already ingenious brains have devised apparatus which, by means of an inclined plane raised or lowered simultaneously with the semaphore arms, rings a bell in the driver's cabin, or admits steam to the whistle. The objection to these devices is that, though they can signal danger, they do not give positive information that the line is clear, and the driver can therefore pass the signal without being certain of his whereabouts.
