关于森铁限坡问题一直存在着争议。一种意见就是各种“选线设计”书的作者奉行的越岭地段的设计原则:充分用足限制坡度,不损失高程,以防线路无为的展长。由此看来限坡长度不应受什么制约。另一种意见是来自生产第一线的工人、干部、技术人员的反应,他们认为列车行驶在长大坡边上,容易出现水汽供应不上,时常出现运缓,影响通过能力,阻碍生产任务的完成,冬季尤为严重。 There has been controversy over the Lim-Sum slope restriction. One of the opinions is that the design principles for the various sections of the Yuelu Mountain that various authors of the “Route Selection Design” put forward are: full use of footprints to limit the slope without loss of elevation and to prevent inaction on the route. In view of this, the length of slope should not be subject to any constraints. The other opinion comes from the reaction of the workers, cadres and technicians in the front line of production. They think that when the train runs on the edge of the long and large slope, the water vapor supply is not easy to come by and there is frequent slow down, affecting the capacity-passing and hindering the production tasks The completion of the winter is particularly serious.
