In front is a flat car fitted with a 2-inchpipe across between the rails and a 2-inch swingpipe on each side, all these pipes having slots onthe under side. The supply is brought from atank car to these pipes by a 4-inch main. Theregulating valves and swing pipes are all con-trolled by levers or handles on the flat car. Withpiping swung out, a distance of 15 to 20 feet ofroadbed may be sprinkled.* Those who have. Fig. 342.

Fig. 342 shows the plan and elevation of aflat car, indicating the method of arranging thepipes filled for the purpose of sprinkling trackwith oil. Crossings.—Road crossings should never, ifpossible to avoid it, ])e made where the track islaid in a cut. They should be of ample widthand easy grade; they are generally made byplanking spiked to the ties; good results, how-ever, have been secured by placing a plank ateach rail
