Abstract

Based on the experimental monitoring results, the paper identifies the influence of non-traffic load (water, snow, frost) on the track substructure freezing, depending on the track routing method (embankment, cut).

The paper introduction characterizes two railway track models (scale 1:1), which are a part of the Experimental Stand DRETM, (in the influence assessment the 1st measuring profile - embankment and the 5th measuring profile – cut are applied). The second part of the paper presents the results of the experimental monitoring and subsequently the comparison of both measuring profiles, in regard to the achieved value of the track substructure depth of freezing. The paper conclusion evaluates the influence of the railway track routing on the thermal regime and on the track substructure freezing.
