What reading level is Automatic Block Signals And Signal Circuits American Practice in the Installati book?
To quickly assess the difficulty of the text, read a short excerpt:
The operator at block tower 23, for example, governs the levers at 24, this consecutive arrangement being necessary for safety. It is evident, also, that each operator has control over trains moving in both directions.
In Fig. 109 the relation of such a single-track system, with the Leonard scheme of control, is shown. D is a track instru- ment (a device which closes a circuit when the wheels of a train pass over the end of a projecting lever whose other end operates a spring contact, as in Fig.... 95) which closes the circuit of the battery, F, through the lock instrument, E. In this same circuit is a circuit breaker, G, which disconnects E from F. A circuit closer, A, is situated at the ends of the east- and west-bound sidings, and is connected to E and F by the line wires, K, L. (The west-bound apparatus is distinguished by small letters. ) The operator, to allow an east-bound train to proceed from 23, unlocks the signal lever at the latter point. The unlocking current passes over the line wires w, which connect successive towers.
