The Rail-Traction wet rail improver formulation has been developed and tested over a number of years in conjunction with South West Trains and the Network Rail Alliance Team who were tasked in finding a solution to mitigate the effect of low adhesion on the railway network.

The Alliance Performance Improvement Team anaylised past incidents which showed that the likely cause of 60 percent of station overruns and other performance issues were related to wet rail conditions. The
majority of these over runs were by less than half a coach length or less than 10 meters.

Existing wet rail mitigations such as high pressure jetting and traction sand are not totally effective at improving adhesion under these conditions.
