The Delhi Metro Rail Corporation (DMRC) has successfully implemented a rail grinding program to address surface defects like corrugation and rolling contact fatigue. Operating 390 km of track, DMRC’s corrective and preventive measures have improved rail conditions significantly since 2009, leading to reduced wear rates and enhanced wheel/rail dynamics.
The article discusses advancements in wheel condition monitoring technologies, particularly by Mermec and MxV Rail. Various methods, including optical and strain gauge systems, gather data on dynamic forces and out-of-roundness. Enhanced systems promise improved predictions of hunting behavior and overall wheel integrity, increasingly complementing traditional inspection techniques in railways.
The article discusses the significance of wheel/rail interaction in railroading, emphasizing the importance of both wheels and tracks. Advances in monitoring technologies, such as continuous wheel condition monitoring and load detectors, enhance safety and maintenance. It highlights challenges and improvements in measuring forces effectively, contributing to efficient railroad operations.
By Jeff Tuzik The unforgiving environment of the wheel/rail interface creates many damage mechanisms. These manifest in defects as varied as corrugations, rolling contact fatigue, and gage-corner cracking, to name only a few. Among the most vexing defects that commuter, transit and high-speed rail lines contend with are squat-type defects …
by Jeff Tuzik In order to solve a problem, you have to be able to measure it. And while there are generally no new problems in railroading, tools and techniques of measurement continue to evolve. Over the years, engineers at the Union Pacific Railroad have noticed a deficit in traditional …
By Jeff Tuzik For over 20 years, the Wheel/Rail Interaction conferences have brought together railway industry professionals, researchers and suppliers to share their expertise in the field of wheel/rail interaction. Until recently, the conferences have been held only in the United States and have drawn on North American experiences. In …
