The history of railway construction in permafrost zones in Russia, USA, Canada and China has extended more than 100 years. Nonetheless, no one has ever been able to build a railway track not subject to deformation caused by subsidence resulting from ice-rich subgrade soils thawing. This paper presents data on the roadbed state in the Zabaikalye and the Qinghai-Tibetan Railways as well as the Baikal-Amur Mainline. It also covers the possibility of roadbed stability maintenance using methods based on the reduction of the mean annual ground temperature and roadbed preservation in a permafrost state by means of the natural cooling and heating factors ratio regulation resulting in a reduction of the heat generation in the roadbed and the adjoining area accompanied by an increase of heat consumption. The research results on the Qinghai-Tibetan Railway and the East-Siberian Railway are given.
