Railroad operation improvements announced

摘要

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.
