VIEW OF A THREE THROW SPLIT SWITCH. by adding a third lead track B, and using slipswitches, cars can be taken from the center ofthe storage tracks to the main line or from onestorage track to another. Fig. 220 illustrates theconstruction of a combination slip switch cross-ing. A view of a three throw split switch isgiven by Fig. 221 and Fig. 222 shows the con-struction at the switch points. In laying out sidetracks and yards, the correctlocation of the frogs and rails from the headblocksto the frogs and from the frogs to the sidings is amathematical problem, though it is often done by 368 BUILDING AND REPAIEINQ RAILWAYS.
