Abstract The load of wheel will effect the geometrical shape of track. It has great influence on the security of train. 1n this paper, a finite element model of track has been established. The decrease of clamping force of fastener, the gauge widening and the rail overturning are discussed.

Key words： clamping force of fastener gauge widening rail overturning finite element
