by Jeff Tuzik Noise and vibration-related issues may not be the first concern that comes to mind in considering wheel/rail interaction. But in the rail transit industry, noise and vibration are king. Complaints about noise, in particular, can put immense political and financial pressure on transit agencies, so mitigating these …
by Jeff Tuzik Noise and vibration mitigation have been driving forces in the design and maintenance of Seattle’s Sound Transit light rail system. Controlling wheel/rail-generated noise experienced by riders and tenants living and working near the track is one challenge; transit agencies around the world must contend with it. Mitigating …
By Jeff Tuzik Sometimes it’s easy to tell that a rail needs maintenance. Excessive rail wear, surface damage, profile degradation, and other issues are unsubtle, if severe enough. But knowing that rail grinding is in order isn’t the same as knowing where to start. Developing and implementing a grinding program …
By Jeff Tuzik In India, rail freight traffic is increasing rapidly. To accommodate the growth, the government has funded and overseen the ongoing construction of dedicated freight corridors in high-traffic-density regions. For the two corridors now in operation, there is a new focus on developing and implementing an optimal rail …
by Jeff Tuzik The track system is a remarkable feat of engineering. To the uninitiated, it can appear simple, mundane. But those charged with constructing or maintaining it know that it’s a marvel of design, that has been continuously updated since its inception roughly 200 years ago. “We take loads …
by Jeff Tuzik Vehicle stability is of paramount concern in the rail transit environment. It affects safety, ride quality, and wear and damage on the track, wheels, trucks, and suspension. In turn, stability is largely defined by the interplay of track characteristics, wheel and rail profiles, and truck and suspension …
