Track lateral resistance ensures the track stability under operation and during its service life in lateral and longitudinal directions. Numerous methods and techniques have been considered to enhance track lateral resistance. Since sleeper, as one of the railway track superstructure components, has a significant contribution in providing the lateral resistance, using different types of sleepers, like Y-shape one, would alter the track lateral resistance. The utilization of Y-shape steel sleepers in railway tracks needs further investigation to comprehend the structural behavior. Hence, in this paper, the lateral resistance of the Y-shape steel sleeper was experimentally investigated by performing the lateral track panel loading test (LTPT) and single tie push test (STPT). The longitudinal resistance force (LRF) in STPT depends on the loading direction. The LRF was specified as 16 kN in Y-top direction and 13 kN in Y-bottom direction for a single sleeper. The LRF in STPT was enhanced by 90% on average compared to the conventional concrete sleeper. The LRF in LTPT was also obtained as 18 kN, and its increasing percentage was measured as 12.5%.
