What reading level is Railway Block Signalling the Principles of Train Signalling And Apparatus Fo book?
To quickly assess the difficulty of the text, read a short excerpt:
the contact, i, and depression of the treadle can only release the lock of the instrument when the contact, i, is complete. The bar, 3, is sufficiently long to ensure its being depressed by at least one wheel of any vehicle, and thus prevents the contact, i, from FIG. 123.
being closed until the last vehicle entering the siding has cleared the fouling bar.
Another piece of apparatus described in the paper by Mr. Hollins, already referred to, is Sykes's signal selector, which is shown by Fig. 12...3. The apparatus "RAILWAY SIGNALLING. 321 is intended for use where a number of signals are vfixed upon one post, and provides for the working of any one of the signals by one lever, the signal arm lowered on any occasion being dependent upon the position of the points. As will be seen from the diagram of connections (Fig. 123) a line wire is run from each set of points to the signal post, and a battery wire to all the points contact boxes, the latter being in series. When all the points are as shown, the circuit is completed through the most distant point box, and operates the signal for the straight road.
