The Muskerry Companys gage is 3 ft., andthat of the Cork & Passage Company is being converted from 5 in. to a 3 ft. gage. A section of double track construction is ^t]M,S^Qllwian%\lcW shown in Fig. 6. The rails form the return circuit, and arc elec-trically connected at each straight joint by two No. coo B. & bonds. 35 in. long. At every switch there are two spanning the steel casting, and there are also for each switchft)ur 35-in. bonds, arranged as shown in Fig. 7. At each crossingthere are tour No. 000 H. & S. 3S-in. bonds. The rails are cross-. FIG. S.—CORK TRAMWAYS. bonded every 240 ft., and where double tracked, the tracks are alsocross-bonded in every 240 ft. These tracks cross bonds are placedhalf way between the rail cross bonds. Where there is doubletrack with central poles the cross bonds between the two tracks arc7 ft. long, and where there is double track with side poles, 5 ft. the cross bonds on single track are 42 in. in length. In all theloops on the single line there is a cross bond between the twotracks. The return circuit is continued over the river at Parnellbridge by four m. cables, connected by bonds to therails on either side of the water; this arrangement is necessary toavoid any inturruption in the circuit when the bridge is swung trolley wire is of hard-drawn copper, double throughout. wire system, with 460 volts between the outer ones, the mains inthe majority of cases consisting of jute covered, lead sheathed, tapearmored cables, laid direct in the streets.
