This article deals with the fire safety test of polymer sleepers in the ballasted track. Although the occurrence of a fire in the track is unlikely, it may occur, for example as a consequence rolling stock fire or arson. In the past, old rolling stock assembly or track maintenance could lead to fire. For these reasons, products installed in track must be fire-safe. A new trend in the sleeper development is the utilization of polymer-based materials that suitably combine the beneficial properties of prestressed con...

This paper focuses on the transmission of loads imposed by passing trains to railway aggregates utilizing a pressure paper method, which enables the quantification of contact parameters on the interface between the railway sleeper bottom and railway ballast. Modern railway ballasted tracks consist of railway sleepers which fulfil especially the functions related to holding rail strings in the gage and inclination, enable fastening system installation, transmit forces and finally spread wheel loads on the ballast m...
