Continuous welded rail has many advantages over the conventional jointed rail. however It may cause high longitudinal force by temperature variation. Because the longitudinal force is very important among various parameters that depend to prevent the track buckling and that influence in effective maintenance procedure, In this paper, We shall present a approach for the prediction of rail longitudinal force using beam-column theory. Various parameters such as track modulus, ballast resistance, and unfastended length are considered effectively and rationally. After a spot verification, new longitudinal force measurement system may be developed using proposed equation.
