. Electric locking . -Ox^ a/ \1 Bt FIG. FIG. 181. described with signal 8 cleared. In Fig. 180 westbound trainmovements will be protected by BW and CW stick relays andeastbound movements by CE and BE stick relays. The latterrelays are not shown, as their control will be similar to thatindicated. Fig. 181 shows the selections for stick relay pick-up 172 SECTIONAL ROUTE LOCKING and stick-up wires. The sectional route locking is assumed to beeffective with signal 1 cleared, while for electric locking in theopposite direction the arrangement will have to be stick relays

The sectional route locking is assumed to beeffective with signal 1 cleared, while for electric locking in theopposite direction the arrangement will have to be stick relays are required for track sections B and C,as shown, and the same for eastbound train movements. Selec-tion whereby BW is shunted out of track section A and signal 1when switch 2 is reversed is necessary. CW relay can be con-trolled through BW stick relay instead of the track sections andcan shunt out when 3 is reversed. With lever 4 reversed CWwill be controlled by other signals and track sections, as explainedin previous systems. Applications
