LAYING OF CONTINUOUSLY WELDED RAIL TRACK IN EXTREME CLIMATIC CONDITIONS
Abstract
The article considers issues of track laying in extreme climatic conditions of Trans-Baikal region, features of heavy trains and new locomotives of Ermak type operations atZabaikalskaya railway [Trans-Baikal branch of JSC Russian Railways]. The interrelation of key indicators for the construction of continuously welded rail track (CWR) is set. They include stress-free temperature, annual temperature amplitude, critical radius and speed of traffic. Technical solutions are suggested that provide electric locomotives with necessary dynamic, speed and other performance characteristics, as can allow well as reduction of the cost of laying and maintenance of CWR.
