Abstract. Determination of the interaction forces between wheel and rail of railway vehicles is essential for assessment of the vehicle dynamic characteristics from point of view of running safety and rail loading the vehicle and alignment them to the Technical Specification for Interoperability. The direct measurement of transverse and vertical interaction forces using the existing full-disk wheel is practical impossible due to the impossibility of separating the two types of forces. To avoid this impediment it was realized a measuring wheelset fitted with 12 spokes achieved as force transducers for measur the vertical forces and 12 spokes achieved as force transducers for measur the transverse forces. The measuring wheelset was calibrated as a force transducer and was used to determine the wheel and rail interaction forces for LE-MA 6000kW electric locomotive by Softronic Craiova. rticle presents the measuring wheelset, the calibration principle and the calibration characteristics as well as time history of the main parameters running safety and rail loading, determined in the on-track tests.

An overturning safety statically procedure for a road rail machine, with a dual rolling system road and rail, in railway disposition it is show in the present paper. It is analyses the load distribution of the pairs wheels of the machine.
