FIELD: transport. ^ SUBSTANCE: invention relates to appliances intended for testing diamond switches in conditions corresponding to their operating conditions. Test stand comprises a track section making a tested specimen with its head accommodating a smaller-than-normal-size diamond switch and a rolling body that, given the normal force applied thereon, rolls on over the track section diamond switch profile. ^ EFFECT: probability to forecast service life of certain material for wheel/rail pairs and to define influence of geometrical linear variations, load size and cycles on results of model test series. ^ 5 cl, 4 dwg
