Bridges with adaptive railway track

Paweł Flont, Jan Holnicki-Szulc
The concept of an adaptive railway track, consisting of sleepers initially elevated (with the curvature tailored according to the detected, coming train) and then yielding in a controlled way under the moving vehicle is discussed. The problem formulated as a shape control requiring the minimum integral measure of the track deflection gives, as a side effect, a significant reduction of the corresponding integral measure of the dynamic contact forces between the track and wheels.
