It is the generalopinion of locomotive superintendents that it is not essential thatthe men who run locomotives should be good mechanics. Thebest runners or engineers are those who have been trained whileyoung as firemen on locomotives. Brunei, the distinguished civilengineer, said that he never would trust himself to run a locomotivebecause he was sure to think of some problem relating to his pro-fession which would distract his attention from the engine. It isprobably a similar reason which sometimes unfits good mechanicsfor being good locomotive-runners. It will perhaps interest some readers to know how much fuela locomotive burns. This, of course, depends upon the quality offuel, work done, speed, and character of the road. With freighttrains consisting of as many cars as a heavy locomotive can drawwithout difficulty, the consumption of coal will not exceed from 138 AMERICAN LOCOMOTIVES AND Fig. 39.—Forging a Locomotive Frame. I to i|^ pounds of coal per car per mile if the engine is carefullymanaged. It takes from 15 to 20 pounds of coal per mile to movean engine and tender alone, the consumption being dependent uponthe size of the engine, speed, grades, and number of stops. If thisamount of coal is allowed for the engine and tender, and the balancethat is consumed is divided among the cars, it will reduce the quan-tity for hauling the cars alone to even less amounts than those givenabove. In ordinary average practice the consumption is from 3 to5 pounds per freight-car per mile, without making any allowance forthe engine and tender. With passenger trains, the cars of whichare heavier and the speed higher, the coal consumption is from 10to 15 pounds per car per mile. A freight locomotive with a trainof 40 cars will burn 40 to 200 pounds of coal per mile, the amountdepending on the care
