Influence of the Condition of the Railway Superstructure on Traffic Noise on the Regional Line

Abstract

Most of the railway lines in Slovakia were built in the second half of the 19th century, or until 1918 (the establishment of Czechoslovakia). Except for the post-World War II period, when approximately 71 % of the Slovak lines had to be renewed, limited funds have been spent on repair and reconstruction works on the lines located in the Slovak territory [1]. Nowadays, there is an effort to modernize the main railway lines but also to revamp the local lines. This is also a case of the line section Poltár - Utekáč, where in the near future a sleeper, which is in very poor technical condition, will be replaced by a Y-type sleeper. On this occasion, the impact of the new structure on the noise emission from the sleeper should also be assessed.
