Abstract

Currently, two types of track gauges are currently in use in the Spanish railway network: the Iberian gauge (1668 mm) and the international gauge (1435 mm). In order to allow the passage of trains with a specific gauge, a dual gauge track was developed in which a third rail is added. With that, this particular track requires an analysis of mechanical behaviour. In particular, this study focused on dual gauge track response produced by train loads. To accomplish this task, a new 3-D finite element model was developed and validated with in situ measurements. The results obtained may be used to predict the track stiffness and vertical response with respect to different track parameters and characteristics.
