A guard timber is placed along each side of each rail of the gantleted sand track, and the space between the timbers is filled with sand, giving a depth of about 2 ins. of sand over the rail. If a car gets away from the gridiron tracks, one of the yardmen throws the switch of the sand track, and the car is quickly and easily stopped, while there Is no difficulty in getting it back again.

After the train was stopped, the sand was cleared away, and the train then ran to the main track through the lower switch of the sand track, the total length of this track being 1,300 ft. The device is also used at derailing switches, a train passing a home signal at danger being diverted onto the sand track. CHAPTER 13.--TRACK TOOLS AND SUPPLIES.

First-class tools should always be supplied, as they need cost but little more than inferior tools, while they do better work and last for a longer time.
