Analysis of vibrations in a modeled ballasted track using measured rail defects

Vibrations caused by trains and transmitted to the ground and structures nearby are a known source of problems related to railways. Therefore this phenomenon should be studied in detail to avoid a negative impact in the environment. Within this framework, the article develops an improved version of...
