Track-Bridge Interaction Effects in Heavy Haul Railway Viaducts
When continuously welded rails are placed over a bridge, the track and the bridge interact via the ballast in the case of ballasted track or track slab in the case of non-ballasted track. This interaction, commonly referred to as track-bridge interaction results in force transfer between the track …

Longitudinal forces in continuously welded rails due to nonlinear track-bridge interaction for loading sequences
… stiffness in longitudinal direction between the track and bridge. This additional load occurs as a consequence of the employment of a nonlinear stiffness law which increases the restoring force by a factor of 3 when the situation of the track changes from ‘unloaded’ to ‘loaded’ due to a passing …

Characterisation of bridge-track interaction of a multi-span viaduct subjected to heavy haul loading
… in modern railways. When the rail is built on a bridge, the bridge's and rolling stock's behavior adds additional forces to CWR rails. As a result of the coupling effects of tracks and deformed superstructures, additional rail stresses are superimposed on other forces. These extra stresses are …
