Rail wear in a curved track costs significant amount of maintenance efforts every year. The rail wear is affected by such parameters as train speed, curve radius, and insufficient cant. However, while the effect of train speed and curve radius to the rail wear is relatively well-known, the effect of the insufficient cant has not analytically researched sufficiently. In this paper, the effect of the insufficient cant on rail wear is studied using a multibody dynamics program, the Vi-Rail. The multibody analysis is performed using an EMU train model being operated in the urban railway. The hard track is utilized in the analysis. To identify the relationship between rail wear and insufficient cant. the wear analysis is conducted for various train speeds and curve radius based on the Archard model built in the Vi-Rail program. The analysis result reveals that, as the insufficient cant increases, the vertical and horizontal wear of the outer rail increases, but the wear of the inner rail does not show distinct trend.
