Approximate formulae for calculating wheel/rail forces and rail displacements at rail welds and for wheelflats (TM-TS-082)

The Track Dynamics program calculates the wheel/rail forces etc. resulting from a vehicle encountering an irregularity at the wheel/rail interface (e.g. dipped joint, weld, wheelflat, etc.), for a given set of vehicle and track parameters. However, it is useful to have approximate formulae, which while giving reasonable results in...
