The third rail between an) two sub-stationsconstitutes a continuous section fed from the sub-stations. SUB-STATION AND PLATFORMS AT MAYWOOD at each end. Sectioning of the third rail takes place onlyat the sub-stations. Each sub-station will, therefore, feedboth ways, and as long as there is no trouble on the line,all the third-rail sections on the entire system will be con-nected together through the medium of the sub-station bus-bars and feeder panels, so that there will be opportunityfor the sub-stations to divide the load among each otheras far as the conductivity of the third rail will permit, andin case of an excessive load upon one section, the sub-sta-tion nearest will not be required to carry the total case of a short circuit on any section of a third rail the circuit breakers at thetwo sub-stations thatfeed it will open, andit will be entirely dis-connected.
