FIG. 4.—TRACK BRAKE ON PECKHAM 14-B 3-S TRUCK the shoes over these hinged rail sections, the section of railswung out, and by loosening two bolts the shoe drops out. Thetime required for replacing four shoes on a double-truck caris about five minutes. As stated in the title this brake is an emergency brake. Itis not intended to be used on curves, crossings, switches, etc.,on account of the liability of tearing out the shoes. It is used, ,however, regularly in coming down steep grades, making ser-vice stops on grades, and in many cases for service stops onlevel streets on a slippery track. It is especially valuable for making quick stops in SanFrancisco, on account of the style of cars. San Francisco cars,as a rule, are open on both ends, and have a closed section inthe center. The seats are all longitudinal, thus leaving a kind of a cab for the motorman. The wheel brakes are operated bya lever on the right side of the controller. The track brakelever is on the left-hand side. If a q
