In this paper, possibility of cracks in fast hardening track has been analyzed with consideration of shrinkage of fast hardening concrete. To evaluate tensile stress on fast hardening track, the analysis considers restrain effects by frictions due to subgrade and rail fastener. The analysis results indicated that the maximum tensile stress in fast hardening track increased as the continuous casting length of fast hardening concrete increased. To prevent cracks due to shrinkage, it was investigated that the continuous casting length be less than 66.9 m.
