Abstract: Because it snows frequently in winter in many places in China, it is very important to remove the snow from the turnouts in time. The installation of snow melting devices for turnouts can effectively remove the snow from the key parts of the turnouts, and improve the efficiency of railway transportation. However, after years of use, more and more shortcomings of such devices have been exposed. In this paper, in order to address the current problems, including the vast electricity load of such devices, the high engineering costs and the fact that it starts to snow in more areas in southern China, large, medium and small railway stations in different regions are chosen as examples to study the engineering design schemes and to optimize the design standards of such devices. This paper has important significance for guiding engineering design in this field, and provides technical support for improving related standards and specifications.

Key words: snow melting for turnout, engineering design standard, setting range
