Abstract
The dynamic response of railway track to lateral forces is investigated. Experimental data in the frequency range 50–1500 Hz suggest that track laid on wooden sleepers is adequately represented as a beam (the rail) on a damped elastic support (the ballast). For concrete-sleepered track the railhead appears to move significantly on the lateral flexibility of the web, and a simple continuous model is developed from which its lateral dynamic response may be found.Keywords
