Effectiveness of Ballast Mats in Reducing Ground-borne Vibration Generated by Passing Trains

In built-up areas of major cities Commuter trains and Light Rail Transit vehicles already pass close to numerous residences and other sensitive structures and land uses. When new tracks are needed to accommodate increasing ridership transit authorities have no other alternative but to build new tracks on their right of way. Under those circumstances the new train tracks may be moved as close as approximately 30 feet of existing homes; as a result of this proximity, the ground vibration problems at the adjacent homes become more acute. The close proximity of these homes to the train tracks and the need to mitigate the adverse effects of ground vibration often require implementation of special track support design that would provide reduction in ground-borne vibration. This special track support system can ensure that train-generated ground vibration levels will be acceptable to residents of the adjoining community. Vibration control measures could, alternatively, be directed at the source of vibration, along the propagation path or at the receiver. This paper reports on the use of source treatment which involves installation of special track support system in the form of a resilient ballast mat between the rail and the ties and the ground surface.
