Try not to distort the rail. To tighten pins in the track, or to reshape distorted or enlarged rail openings apply the pliers as shown in Figure 27. Many model railroaders make their own special track pliers by filing a round groove the size of a rail in a pair of flat nose pliers. Besides various straight and curved track sections, many layouts also require the use of track switches and crossings. Track switches are usually sold and used in pairs consisting of left hand and a right hand switch although single switches are available for use in constructing sidings.
Manufacturers make both electric remote control and manual, or hand-operated switches.
Track crossings enable two lines of track to cross each other like a figure 8. Crossings and hand-operated switches need no special wiring of any kind. In sections, the steel track pins make the required electrical connections. Connect the center wire to the middle binding post of the switch. Connect the outside wires to the outside binding posts.
