Railroad operation improvements announced

A locomotive of wide range and notably lower operating and maintenance cost is announced as a general-purpose combination of high speed and heavy drag. General Motors´ GP30 has four motors and four axles, and is rated at 2,250 hp for traction. With about 30 structural and operation improvements, all aimed at increasing the locomotive´s economic value, the GP30´s increased capacity permits operation of present freight schedules with fewer units — two new units replace three older, 1,500-hp units. Its prime mover is the 567-D3 diesel engine that operates at high altitudes with little or no reduction in rated horsepower.
