二十多年来,我国铁路牵引动力的发展取得了一定的成绩。自从1956年制定关于“技术政策的中心环节是牵引动力的改造,要迅速地有步骤地由蒸汽机车转移到电力机车和内燃机车上去”的方针,至今已二十五年了,我们对此还存在意见分歧。主张以蒸汽机车为主的同志认为石油及石油制品的价格还将进一步上涨,因而内燃牵引的有利性将更小,在目前牵引3300吨基础上,蒸汽牵引是比较经济的。但在运量较大的区段,电力牵引是三种牵引方式中最经济的。如
Over the past 20 years, China’s railway traction power has made some achievements. It has been 25 years since 1956 when we formulated the guideline that “the central aspect of technical policy is the transformation of traction power and the prompt and step-by-step transfer of steam locomotives to electric locomotives and diesel locomotives.” There are differences of opinion. Advocates of steam locomotive-based comrades that the prices of petroleum and petroleum products will further rise, so the benefit of internal combustion traction will be smaller, based on the current traction 3300 tons, steam traction is more economical. However, in the larger traffic section, electric traction is the most economical of the three traction modes. Such as
