Excerpt from Block and Interlocking Signals: What They Are for What They Do, How They Do It"What are we stopping for, conductor, out here in the woods This is a limited train. What! stopped by a signal, a block signal, you say Why, what is that Oh, I see! You have a red blade projecting from the top of a pole to indicate to the engineer when the blade is moved up or down whether he may enter the block or not, the block being the piece of track extending to the next signal. So, then, when we are stopped by such a signal it means that another train is in the block, and we will have to wait until it has passed out."And thus it is that to-day trains are being run through towns and cities, over mountains and prairie, through bridges and tunnels, in cuts and around curves with absolute safety, a fact not fully appreciated by the traveling public, but which becomes to the engineer, whose responsibility is lightened and from whom anxiety is removed, a guiding star, telling him that the track is his and that there will be no one to dispute it with him, for such little arguments, you know, arc sometimes disastrous.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
