Different optimal designs of bogie bolster for model 18-100 freight car are examined in the article. There is an analysis of existing bolster designs. Full-fledged fatigue tests by the method specified in GOST 32400-2013 are carried out on the stand designed for dynamic strength tests. The values of experimental studies on the stand were compared with the calculated ones, with maximum loads from 735 to 755 kN. The best results were observed at a maximum load of 745 kN, and the beam lost its bearing capacity at 6.182 million cycles, which is 39% more than the required strength index. The minimum cycles before cracking and before the loss of bearing capacity of the freight railway bogie bolster beam were established.
