Low-cost conversion of bolted track to CWR; fatigue strength of thermit welded flat-bottomed rails in shear (TM-MF-182)

The evaluation of low cost options for converting bolted track to CWR (e.g.) has led to a requirement to evaluate the fatigue strength in shear of bolt holes in rails adjacent to welds. An evaluation of such holes in bull head rail has already been reported. This report provides supplementary...
