Abstract
On the basis of analytical method of studying devices for the application of forces on a rail head and numerical method of calculating structural strength the authors have developed a new device for loading the rail head by vertical and lateral forces. The device that simulates force of wheel influence on rail allows applying vertical force on the axis of symmetry and with the offset of ±20 mm simultaneously with lateral force. Due to the lightened collapsible frame and the existence of roller bearings the device is comfortable in use, which contributes to the increase of speed of tests on the influence on track and researches in this sphere.
