Concrete ties need to be installed on a well-prepared subgrade with an adequate depth on free-draining ballast to perform well. It is a common misconception that concrete ties amplify wheel noise. A study done as part of Euronoise 2018 proved this false, showing concrete sleepers to be an average of 2dB(A) quieter than wooden ones, however with ...
Pre-war experiments with long welded rail lengths were built upon, and in the years from 1960 long rail lengths were installed, at first on hardwood sleepers but soon on concrete sleepers. For example, the first long welded rail (almost 1 mi or 1.6 km) on the UK's East Coast Main Line was laid in 1957, just south of Carlton-on-Trent , resting ...
