Cyclopedia of applied electricity : a general reference work on direct-current generators and motors, storage batteries, electrochemistry, welding, electric wiring, meters, electric lighting, electric railways, power stations, switchboards, power transmission, alternating-current machinery, telegraphy, etc. . with aspace between the heads to allow the car wheel to follow themain rail if it is not to be deflected to the cross-over rail. A shortguard rail assists in guiding the wheel over the cross-over rail. Where the rails cross at an angle, a frog is located. Theconstruction of such a frog is shown in Fig. 237. It is built up ofpieces of standard rail with filler blocks between as shown in thecross-section. A good idea of a complicated piece of work may be obtainedfrom Fig. 238. Here two double tracks cross and they are con-nected with each other by two sets of curves. The switches andmates used here are similar to those shown and in addition thereare right angle and curve crosses. The light lines show the plainrail and the heavy lines the special pieces. The ends of each specialpiece are marked by black circles. The construction of thesecrosses is shown in Figs. 239 and 240, where the rails are heldtogether by cast steel pieces cast in position.
