This necessitated the complete re-newal of some of the old yokes before the placing ofthe concrete, as many of the old yokes were deeper thanthe new ones to be installed. Forms about 12 in. squarewere placed around the bottoms of the supporting tim-bers. The level pouring of this floor greatly facilitatedthe setting up of the new yokes during installation workat night and also served as a spread footing under theentire job. It was necessary to install the new work in threesections. The crossing was installed first, the outsidecurve, including both branch-offs and both curved cross-ings, next and the inside curve and branch-offs last. Asall our installation work has to be done between 1 and. AT TOP, LEFT, SURFACE WORK SET UP ON LOT PRIOR TOJUST BEFORE INSTALLATION OF NEW CROSSING. AT BCINSTALLED.
