Fig. 1 shows a cross section of the conduit, rails and road-bed construction. The feeders are placed in the ducts onthe inner side of the conduit. Fig. 2 is a section through ahand hole yoke. The yokes are at intervals of five feet andevery third one is provided with a hand hole. The mannerof holding the porcelain insulators is as shown. An ironcap is bolted to the slot rail and holds the insulator, into Top of slot Rail
