To prevent the side-running trolley wheels from being pressed into the gaps inpassing them, a grooved track or guide for the trolley wheelguard (d), Fig. 7, is formed in the lower por-tion of the arch at the points (e), Fig. 6, sothat the guard, being of greater radius than thetrolley wheel, bridges the gap and delivers thewheel to the wire on the other side smoothlyand with certainty. Fig. 7 is a plan view,showing the method of bridging the gaps at thecross-overs, while Fig. 8 is an elevation show-ing the relation of grooved guide or track tothe guard, trolley wheel and wire of the und
