controller-rails 212 and 213 a current passes along the controller-rail 213 and wire 216 to contact-point 215 (the points being so set that locomotive may enter siding); thence by contact-point not shown in error in the drawings adjacent to contact-point 215 connected with wire 229; thence to switch of stop-rails at 227, rendering same non-conductors, current passing by wire 228 to switch of stop-rails at place 226 also rendered non-conductors, and returns by wire 228 to wire 219 back to controller-rail 212.

“ And when the locomotive’s depending-rods 79 and 079 make contact with the inner controller-rails 217 and 218 (which are not joined in the outer controller-rails) at place 227, a current passes along wire 219 to the switches in boxes 48 relating to rear stop-rails situated rearwardly of C and B, rendering said rails and relative indicator-rails non-conductors, the current continuing along wire 219 to the switches 044 at places B and C relating to the up journey, and rendering said stop-rails at B and C and relative indicator-rails conductors, the current continuing along the same wire 219 to the switches in boxes 048 relating to the rear stop-rails situated rearwardly of the places D and E, and rendering same with relative indicator-rails conductors, also the current continuing along the wire 219 to the switches 44 at places D and E, thus rendering the stop-rails and relative indicator-rails at said places non-conductors, and current returning by wire 220 to the controller-rail 218 at place 227. Thus it will be seen that the stop-rails and relative indicator-rails at places D and E, and the rear stop-rails and relative indicator-rails rearwardly of places B and C, have been rendered non-conductors, that were previously conductors when the train first arrived adjacent to the siding; but said train is simultaneously protected by the stop-rails and relative indicator-rails at places B and C (using switches in boxes 044) being rendered conductors, and the rear stop-rails with relative indicator-rails rearwardly of places D and E having switches in boxes 048 also being rendered conductors.

“ When the locomotive continues along the siding from the place 227, on making contact with the controller-rails 208, 209, 210, and 211 it cannot render the stop and relative indicator rails (using switches in boxes 044) at places B and C, and rear stop-rails with relative indicator-rails (using switches in boxes 048) rearwardly of places D and E, non-conductors, on account of the solenoid 202 having broken the electrical connection (by virtue of the brake-van being on the controller-rails 194 and 196) between the controller-rails 208, 209, 210, and 211, and the stop-rails (using switches in boxes 044) at places B and C, and rear stop - rails (using switches in boxes 048) rearwardly of places D and E.

“ At the same time, when the locomotive is in contact with the controller-rails 208, 209, 210, and 211 a current passes along from the rail 211 to the wire 230 through the contact-points 231 (which are joined together by the points being so set), continues along the wire 230 through the switches of the stop-rails at places 198 and 199, rendering same conductors, and the current returning by wire 235 and contact-point 231 adjacent to place 199 and wire 207 back to the controller-rail 210.

“ The locomotive before leaving the siding passes over controller-rails 212 and 213, and a current passing along from rail 213 to contact-point 215, wire 216, to the switch of stop-rails at place 198, rendering said stop-rails and relative indicator-rails non-conductors, current returning by wire 214 to the controller -rail 212. Simultaneously the stop and relative indicator rails at place 199 being also rendered non-conductors (the controller-rails 212 and 213 at both ends of the siding being electrically connected). The locomotive is then coupled on to the remainder of the train, and ready to proceed back in the direction it came from.

“ If it is desired to shunt the entire train on to the siding, say, for instance, to allow of a train to pass through, the train is backed down clear of the points nearest to letter D, and the solenoid 202 resuming its normal position upon the entire train leaving the controller-rails 194 and 196 and entering the siding, and upon the locomotive passing over the controller-rails 208, 209, 210, and 211 it will render the stop-rails at places 198 and 199 conductors; but when the points are so set that no other train may enter the siding, and the locomotive making contact with the controller-rails 208, 209, 210, and 211, will send a current along the wire 230, thence to branch-wire 233, contacts 234 at place 198 (the adjacent contact-points corresponding to one another being in contact when the rails are so set that no train may enter the siding), thence by wire 233 to the switch of stop-rails and relative indicator-rails at 198 and 199, rendering same non-conductors; thence the current returning through the contacts 234 at place 199, wire 235, and wire 207 back to the controller-rails 209 and 210.

“ At the same time a current passes along the wire 205 by plunger-contact 202, wire 204, wire 205, contacts 206,

adjacent to place 198; thence through the switches in boxes 044 of stop-rails at places B and C and switches in boxes 048 of rear stop-rails situated rearwardly of places D and E, all being rendered non-conductors, the current returning by wire 207.

“ Thus a train is enabled to pass safely along the main line. The train on the siding desiring to proceed out will, when the points are so set (being still in contact with controller-rails 208, 209, 210, and 211), render the stop-rails at places 198 and 199 conductors (in the manner hereinbefore mentioned), and the locomotive on making contact with the controller-rails 217 and 218 will render the stop - rails with switches in boxes 044 at places B and C, and the rear stop-rails with switches in boxes 048 rearwardly of places D, conductors.

“ It will thus be seen that in the case of a train on the main line and a train on a siding (that is to say, trains on different railway-tracks, either approaching or following one another) each train is enabled to render rails conductors and non-conductors accordingly as the points joining the main line and siding are moved or set, so that a train may or may not, as the case may be, enter or leave, or not enter or leave a siding, the conductors joining the contacts on the siding points or blades being made or broken accordingly as the siding-points are moved, and the operations indicated in Fig. 18 and hereinbefore described may be effected for the purpose of protecting a train on the main line and a train on a siding from the risk of collision.”
