在探讨我国铁路牵引动力现代化的政策中，关于电力牵引技术经济优越性的问题，认识比较一致；关于电气化投资问题，则是看法不一。有人认为电气化投资太大，并举石太线电气化每公里投资高达250万元为例，据此计算，若修建一万公里电气化线路，国家就需要拿出250亿元的投资，几乎相当于目前全国铁路固定资产总和的一半。因此，认为铁路电气化犹如共
In discussing the policy of modernizing railway traction power in our country, there is more common understanding on the economic superiority of electric traction technology, and different opinions on the issue of electrification investment. Some people think that investment in electrification is too large, and take the electrification of Shitaihua as high as 2.5 million yuan investment per kilometer. Based on this calculation, if 10,000 kilometers of electrified lines are to be constructed, the state will need to invest 25 billion yuan, almost equivalent to the current national Half of the railway’s total fixed assets. Therefore, the railway electrification seems to be a total
