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.

Originally published in 1906, "Block and Interlocking Signals" provides a comprehensive analysis of the mechanical systems used to control trains and ensure their safety. With detailed descriptions and illustrations, W. H. Elliott examines the different technologies used in railroad signaling, including the block system and interlocking switches.

Not illustrated. 1896 edition. Excerpt: ... a point between the contact points and the center of gravity of the whole piece, or else the pivoted end will be lifted first, the points being brought together only after the whole armature is lifted. With a weak current, such a fault as this will mean that a relay that otherwise would have been able to do its work will fail to lift the armature, and there will be nothing that a repairman can do to fix it, except, perhaps, to tilt the relay and thus lessen the force of gravity--a thing which is sometimes done with the form of relay alluded to, but which should not be so placed, from the possibility that the armature will not fall back and break the signal circuit and put the signal at danger when a train is in the block. The iron forming the armature should have a piece of paper cemented to the side that is next the pole piece of the magnet, to prevent the two pieces of iron from coming into actual contact with each other. This is done to prevent the armature from sticking on account of polarization, or the residual magnetism that is left in the iron, as iron after once being magnetized will retain sufficient magnetism after the circuit is broken to hold the armature, if the two pieces are in actual contact. Paper is better than a thin sheet of copper soldered to the armature, as it is lighter, and is also much better than pieces of rubber, brass or other non-magnetic material driven in a hole drilled into the end of the core and left projecting above the surface, as the two surfaces have to be separated much further than with the paper, from a possible tilting of the armature bringing it in contact with the pole piece of the magnet. To provide the relay with pointed contact pieces is a very poor arrangement, there being a strong...
