世界上很多铁路,其中包括挪威的卑尔根铁路受冬季冰雪害的影响十分严重。挪威国营铁路平均每年用于除雪机械方面的费用就大约需要一千四百万克郎(挪威货币单位)。选用适当制式的机械除雪犁,安装防雪栅,防雪棚等固定除雪设备,用加热及其它保护技术都可以有效地除线路上、道岔区、转撤机拉杆及轨枕底部的积雪,保证冬季铁路运输畅通无阻。而要清除挪威国营铁路4,240公里线路上的积雪保证全线在整个冬季的正常运营,则需要大量的劳动力。这在当前来讲无论如何是难以被人们所接受的。最近几年,挪威国营铁路已经越来越多地使用了除雪机械,即使如此,在最近几个气候比较暖和的冬天,每年用
Many railroads in the world, including the Bergen Railway in Norway, have been severely affected by winter icy and snow damage. The Norwegian state-run railway costs an average of 14 million kronor (Norwegian currency) on average each year for snow removal machinery. Use the appropriate standard mechanical snow plows, install snow guards, anti-snow shed and other fixed snow removal equipment, with heating and other protection techniques can be effectively in addition to the line, turnout area, withdrawal drawbar and sleeper bottom of the snow to ensure that the Winter Railway Unimpeded transportation. And to clear the snow on the 4,240-kilometer line of the Norwegian state-run railway to ensure normal operation throughout the winter requires a great deal of workforce. It is hard to be accepted by people anyway at this moment. In recent years, Norwegian state-owned railways have been using snow removal machines more and more. Even so, in the warmer winter months in recent years,
