Abstract: This invention relates to a device for determining lateral and/or vertical deviations in the path taken by a wheel at railway points or crossings. One of the aims of this invention is to provide data on the condition of such points or crossings, particularly as to the degree of their wear. Further, it is another aim of the invention to create a device which is easier to relate the signals from the sensors to the direction of the loads giving rise to these signals, and which at the same time is simpler and more economical to assembly while at the same time ensuring reproduceable results.
