Measurements of noise of diesel motor train of series ŽS 711

Abstract

Serbian Railways recently introduced several new types of rail vehicles in operation. In 2012, multiple diesel unit of class 711, manufactured by Russian company “Metrovagonmash” was purchased by the Serbian railroad operator. These train units are expected to replace old diesel rail-buses that operate on sections without electric power, and, therefore, to become the dominant type of rail vehicles on Serbian local railway lines. This paper presents results of measurements of the equivalent level and one-third octave spectrum of noise emitted by a stationary unit of class 711 and a class 711 train moving at constant speed. All measurements are performed according to the ISO 3095:2013 standard.
