Rail Tamping Operation Jul 05, 2018

Rail Tamping Operation


1. Why do we do tamping operation?

    Due to the result of train operation or the effect of natural environment, part of the ballast of the track bed falls into the bed of the roadbed, which causes one side or two sides of the rail to sink, forming small pits and triangular pits. The irregularity of track cross section affects the safe operation of train.
