Kalker's FASTSIM program and variation of contact ellipse were introduced for curving simulation of a non-pendulum rail vehicle. Digital simulations of curving for a representative example were made. It was shown that spin creepage increased steady value of lateral wheel-rail force by 28% and decreased dynamic value when passing random track irregularity by 11%, while variation of contact ellipse decreased steady value by 7% and increased dynamic value by 3%. It was also shown that spin creepage plus variation of contact ellispe increased maximum value (steady value plus dynamic value) by about 10%. A method of curving simulation considering almost all important factors was established by this report and the previous report^<(1)>
