Abstract

As train velocity increases, aerodynamic problems become increasingly important for railways. In open sections, passing of a train nose, train tail and pantograph shield generate pressure variation along the wayside to cause environmental problems, such as rattling of window frames and shutters of houses near the railway. These phenomena are classified as infrasound. It is necessary to solve the problem of operating high-speed trains in the densely populated residential areas along the railways. This paper describes the results of recent researches conducted to develop effective countermeasures to reduce the pressure variation. We investigated the effect of the pressure barrier and train nose configuration as countermeasures.
