The Sutter Street line is one over which there wasa great deal of discussion on the part of the property owners, heavier rails—involved no unusual difficulties. The concretebed was broken away from around each rail, the iron-platecross ties were sawed off a few inches, and the new-rails werebolted to double angle-iron chains, whose upright connect-ing plates were bolted to the ends of the cross ties. The formof support may be noted in the accompanying illustration.No change was made in the cable slot. The matter of widening the distance between track centers,however, was a more difficult operation. The tracks wereoriginally 9 ft. 6 ins., center to center, and while the new railswere being laid it was deemed advisable to widen this distanceto 10 ft. This latter is the width between track centers on

As anunderground system was shown to be not practical at thepresent time, and as an overhead trolley was objected to, thequestion was settled for the time being by the railway com-pany agreeing to improve the present cable service. The first step toward this improvement concerned the trackand the new work consisted in making three distinct changes;first, the old light cable rails were replaced by heavy 7-in.steel girder rails in 6o-ft. lengths; second, the distance be-tween centers of tracks was widened, and, third, it was pro-posed to change both tracks from the present 4-ft. 12^- in. tostandard gage.
