In this way the proper position of the rails is secured inan exact manner, and it is only necessary to align and levelthem, which is easily done by adjusting the position of thewooden timbers. In other words, the track is aligned by means. INSERTING MOULDS IN TRENCH of the slot rails, which is the end desired, and the rest of thestructure is made to conform to it. The next process is toattach the yokes to the slot rails, which is done by means of fourbolts. The brace rods connecting the web of the slot rails withthe yokes are then put in place. The only work now remainingto be done is to build up the conduit proper.

It consists of three parts, a semi-circular piece made of wood and marked A., and two verticalpieces marked B. This mould, as shown in the longitudinalsection, is made in two partsheld together by bolts and pinsso that it can easily be takenapart and removed from theconduit after the concrete hasbeen packed in place.
