A designfor a pump house and machinery is shown inFig. 175; this shows a gasoline engine belted toa pump. To supply locomotives with water largeamounts are required at intervals more or lessfrequent depending on the number of trains. Toobtain an economical plant, provision must bemade for storing the water as it is pumped andrunning the pumping plant steadily; this per- 260 BUILDIXG AXD KEPAIRIXG Fig. 172. PUMP FOR A DEEP WELL.

The water tanks generally usedare 16 feet high and 24 feet in diameter and con-tain 50,000 gallons. They should be placed highenough above tlie rail to give the water sufficientforce to fill the tender rapidly and not unneces-sarily delay trains; some roads are placing thebottom of the tank twenty feet above the tanks are made of wood and are supportedon wooden or iron posts.
