以上就是自己从新闻中琢磨出来的一点点东西,水平有限.不足之处,各位多多指教.
<p></p><p></p><p>楼主对火车这么了解,楼主是搞铁路专业的吧.</p>
楼主强悍,严重支持!

问句外行话:既然内燃机车在高原功率下降很多,为什么当初不考虑采用电力机车?电动机应该与空气厚薄无关吧?是电力机车成本高?还是其他?
&nbsp;&nbsp;&nbsp; 好帖!顶一下&nbsp;&nbsp;&nbsp;
<p>顶!!楼主太强了!!!</p>

楼主不是一般的强悍,近来崇拜一下

<p>楼主果然是高手,分析的很透彻啊!</p>
高高,偶学习
<p>kutoo:</p><p>&nbsp; 电气化的运输能力是非常大,在青藏线这样特殊的地区和内燃比较更具有环保优势.青藏线没有选择电气化的主要原因在于电力供应没有办法保障.西藏本来就是一个电力供应比较缺乏的省份,大型的水电和火电基地离西藏都太远了.所以青藏线现在暂时还不使用电气化,以后有条件的时候一定会上电气化的.</p><p>&nbsp;&nbsp;</p>

高原上有滚地雷,也就是接地的闪电,对电力设施的破坏很严重.所以青藏铁路不可能用电力机车.

很专业的铁路机车知识,我也觉得用电气机车可能更好,不过现在实现有困难。
楼主在分析的时候忽略了一个重点:单/复线。<br/>从7月1日当天的电视新闻来看,青藏铁路的所有桥梁和隧道都是单线,没有预留复线空间(隧道是否预留了电气化净空也很难说)。这意味着至少在可预见的将来,青藏线将是一条单线铁路。由此将会对运力造成极大的制约。
