Monitoring the Dynamics of Railway Tracks by Means of the Karhunen—Loève—Transformationrate significant information from the enormous amount of data collected from measurements the Karhunen-Loève-Transformation (KLT) is employed. It is shown that KLT is an efficient tool for information compression and for displaying the severity of a track failure. Our project was worked out in close cooperation with Deutsche Bahn AG (German Rail).

Wavy Wear Pattern on the Tread of Railway Wheels actual contact conditions. Starting from small initial irregularities the evolution of wavy wear on the treads is simulated numerically. Depending on the running conditions the wear pattern differ with respect to profile and waviness. The results correspond to observations.

On the Numerical Analysis of the Wheel-Rail System in Rolling Contactceptual comments for the extension for transient rolling contact are made. Numerical examples for three dimensional simulations including rolling over worn profiles demonstrate the applicability of the developed program package. A prospect of started key issues of research and development finalizes the paper.

Rolling-Contact-Fatigue and Wear of Rails: Economic and Technical Aspectsrailways companies. It is shown that a lot of work has already been done, but there is still a need for further investigation. Research work on Rolling-Contact-Fatigue and its relation to wear and economics is one of the fields of investigation which needs further support by government, industry and
