By Huimin Wu and Semih Kalay • January 2010 See Part 1 of this article here. What are the differences between rail shapes that produce higher contact conicities and those that produce lower contact conicities? The profiles shown in Figures 1a and 1b illustrate the differences that can result in significant …
By Jeff Tuzik • July 2010 Wheel/rail interaction is complex, variable and difficult to manage—especially on rail transit systems where noise, vibration and ride quality present daily challenges. As a result, managing the wheel/rail interface requires constant attention and innovation. Speakers at Advanced Rail Management’s Rail Transit 2010 seminar on …
By Rob Caldwell • October 2010 The wheel/rail interface is a complex system – one that benefits greatly from careful pre-engineering. There are significant benefits from properly addressing the wheel/rail interface, and serious consequences from allowing the interface to govern itself. While there are examples of both pre- and post-engineering scenarios, there …
