Cover Story: This paper evaluates the performance of a new prestressed bearer for turnouts, designed for the 1000 mm gauge in Vietnam. The study involves six tasks: conducting a literature review, developing the proposed bearer structure, preparing test samples and determining design load, conducting laboratory tests, analysing test results, and making recommendations about the carrying capacity of prestressed bearers for railway turnouts using the arrangement of prestressed strands and laboratory testing. Test samples of PSB were manufactured in the factory. The bearers were tested in the laboratory with three tests: a positive bending moment test, a negative bending moment test, and a fatigue test. The proposed bearers for turnouts meet the carrying capacity requirements under static and fatigue loads.
