Canadian engineer . gnal,to give information of proceed, stop, and as to position ofthe signal ahead. This was deemed necessary for engine-men and trainmen in the safe handling of trains at reason-able speed, and results have shown the absolute safety andreliability of the practice. At Lake Street use was made ofthe third position on the last signals .governing trains in-bound into the depot to indicate that the track under thetrain shed is clear. The dwarf signals (Fig. i) are motor driven and, exceptat the Lake Street iplant, all dwarf signals are used in twopositions only, viz., horizontal and diagonal. Inasrauoh as the signaling andl interlocking of a largeterminal is installed as much for the acceleration of trafficas for its protection, the means of receiving and giving in-formation and of communication is one of the important fea-tures, and was, therefore, given a great deal of attention,and in the solution of the problem almost everything wasconsidered. The telegraph was dismissed from considera-. Fig. 1. tion almost immediately, as it restricted too closely the sourceof supply for levermen to operate the plants and for towerdirectors. The various means finally adopted and usedwere :— Conductors-towermen-gatemens system of Various forms of automatic train annunciators and indi-cators. Illuminated track over system. In oi)crating the system for through trains, the con-ductor pushes his batten one minute before time for histrain to leave. This lights the top light on the towerdirectors table and the first light of the gatemens indicators,reminding the tower director and gateman that it is nearlytime for the train to leave. The tower director, if he canhandle the train on time, immediately pushes his button,which action puts out the top light and lights the secondone on his table, puts out the first and lights the secondone at the gate, and lights the top light of the conductorsin
