USE OF NUMERICAL MODELS TO DETERMINE THE EFFECTIVENESS OF ANTI- VIBRATION SYSTEMS FOR RAILWAYS

Vibration from trains can cause annoyance and also concern about possible damage to property. It is a major issue in the environmental impact assessment of new railways and where new traffk is to be added on existing railways. Track designed to control vibration has been implemented on a number ofrailare effective for ways. These designs vibration at frequencies at the L w end of o the audible range. Such vibration causes re-radiated noise in buildings and is especially associated with trains in tunnels
