The Clinician–Educator Track

Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

The Netherlands Schedules Track Maintenance to Improve Track Workers' Safety

After several fatal accidents, improving the safety of rail-track workers became a political priority in The Netherlands. Maintaining the track was one of the most dangerous jobs in the country. ProRail divides its infrastructure into working zones to be taken out of service during maintenance. We developed a two-step method of constructing a four-week maintenance schedule in which each working...

A Study to Predict the Development of Wear for the Wheel/interface of a Railway Track

The train transport is often confronted with greatly repeated changes in scope, vehicle travel well-being and transport safety because of the adjustments of wheel and rail profiles. These problems are frustrating and threatening. Thus, there is a requirement for an approach to predicting the wear of wheel/rail to tackle these problems. A new theoretical ground is broken through the build-up a m...

On the right track.

Suppose that everyone accepted the statement ‘Twice two is five’, simply because they used the numeral ‘five’ in the way that we currently use the numeral ‘four’. Would that make twice two five? It wants only a modicum of philosophical sophistication, combined with some awareness of the difference between mentioning an expression and using it, to answer no. Now suppose that everyone believed th...
