Tie type is one of the most effective parameters for changing the lateral resistance of ballasted track. In this study, the lateral resistance of an existing curve-to-lateral movement is investigated in the field in two conditions: with simple mono-block concrete ties (B70) and with friction concrete ties (B70F). After that, lateral resistance is measured through the panel displacement method. The results show that the lateral resistance of the railway track increases by approximately 67% with the use of friction concrete ties (B70F) instead of standard mono-block concrete ties (B70).
