OPTIMAL POWER IN ELECTRIC LOCOMOTIVES

After reviewing the rise in specific power of European electric locomotives since 1920 from 10 to 35 hp/1000 lbs, the author expresses surprise that in planning for electrification in the United States, the Department of Transportation, the railroads, and the utilities are basing their plans on more or less a modification of the existing diesel electric locomotives with relatively low power or 5100 rail hp on 6 axles with the same small wheels and axle-suspended traction motors etc. as for the existing diesel-electric locomotives which gives a specific power of only 14 hp/1000 lbs. On the basis of European experience, it was described that the 2 locomotives EMD is manufacturing for demonstration in the US will have 31 hp/1000 lbs or 11000 hp pro 6 axles. The paper then proceeds to explain in detail the operating and economic advantages of the more powerful locomotives, considering some specific American coal-hauling routes.
