Pressure cell results for a ballasted railway track section tested in the CEDEX Track Box
Pressure cell results for a ballasted railway track section tested in the CEDEX Track Box
CEDEX Track Box (CTB) is a 21 m long, 5 m wide and 4 m deep facility whose main objective is to test, at 1:1 scale, complete railway track sections of conventional and high-speed lines for passenger and freight trains, at speeds up to 420km/h. Its special characteristics allow the testing of different railway sections, types of trains, passing by velocities and materials in advance of their use in the real railway. In this work, we present the results obtained from pressure cells located at several depths inside the railway track section, after testing two different types of trains at eight different passing- by speeds (from 50 to 400 km/h). The railway train section tested in this work has the same requirements as the Spanish ballasted high-speed track sections. These tests show the distributions of pressures underneath the superstructure and how they are affected by the different loads of each type of train and the several passing-by speeds.
