Abstract
Nowadays, the social importance of the railway transportation is accepted without any doubt, and the levels of comfort and operation quality associated to railways are continuously increasing. The travel times that could be considered allowable in the past century are now obsolete and in order to reduce time “losses”, traffic speeds larger than 300 km/h are being asked for. In order to analyse properly the behaviour of the different layers that make up the railway track structure, the Centro de Estudios y Experimentación de Obras Públicas (CEDEX) of the Ministerio de Fomento, Spain, has built a large facility (5 x 4 x 21 m) for true scale testing where, by means of several dynamic actuators, the passage of high speed railway traffic can be reproduced, and its long term effect on the track materials can be studied. This paper describes the facility from a structural standpoint, including the self-controlled actuators and the instrumentation that has been laid out prior to the test being carried out. Finally, the most relevant results, than can be obtained in dynamic tests, are shown.
