Sound Transit Studies Wheel/Rail Interaction Differences Between Vehicle Types

April 23, 2023 | Filed under: Rail Transit, Vehicle/Track, Wheel Maintenance, Wheel/Rail Interaction

by Jeff Tuzik Seattle’s Link Light Rail, operated by Sound Transit, is a fairly young system. And by most standards, a small system. But it’s also a sophisticated system, and it’s growing fast. The system currently operates 25 miles of track and is in the midst of expanding to 50 …

Wheel/Rail Interaction ’08: Data to Information (Part 2 of 2)

January 4, 2014 | Filed under: Friction Management, Measurement Systems, Rail Grinding, Wheel Maintenance, Wheel/Rail Interaction

By Jeff Tuzik • October, 2008 Part 1 of this article examined efforts to optimize vehicle and track component performance through various testing, monitoring and simulation programs. Part 2 continues on the theme of “data to information,” further exploring such programs and the operational benefits they engender. Maintaining a Safe Neutral Temperature (SFT) on …

Wheel/Rail Interaction ’08: Data to Information (Part 1 of 2)

January 4, 2014 | Filed under: Measurement Systems, Rail Grinding, Vehicle/Track, Wheel Maintenance, Wheel/Rail Interaction

By Bob Tuzik • July, 2008 As research into wheel/rail interaction has evolved, the emphasis has moved toward implementation of available technology and conversion of data into information. Such was the case at Wheel/Rail Interaction ’08, the 14th annual seminar produced by Advanced Rail Management and sponsored by Progressive Railroading magazine. Railroaders, researchers …

Identifying Causes of Out-of-Round Wheels: Measuring Field Experience Against Simulations

January 4, 2014 | Filed under: Wheel Maintenance

By Bernhard Barkow and Paul Mittermayr • October, 2008 The interface between the wheel and rail represents the central link in railway dynamics. Imperfections, such as out-of-round wheels, have a significant effect on vehicle and track maintenance costs, and on safety and passenger comfort, as well (1). Much research has been …

Managing Wheel/Rail Interaction on Rail Transit Systems

January 4, 2014 | Filed under: Rail Grinding, Rail Transit, Vehicle/Track, Wheel Maintenance, Wheel/Rail Interaction

By Bob Tuzik • January, 2008 All railways must deal with operating/engineering and vehicle/track interaction issues. But rail transit systems, which operate under the microscope of the urban environment, face special, often unique, challenges. Speakers at Rail Transit ’07, Advanced Rail Management and Interface Journal’s third seminar devoted to wheel/rail interaction on rail …

Wheel Re-Profiling and Rail Grinding Strategies on Wiener Linien (Part 2 of 2)

January 4, 2014 | Filed under: Rail Grinding, Wheel Maintenance

By Edgar Fischmeister, Markus Ossberger, Roman Pongracz and Paul Mittermayr • January, 2008 Part 1 of this article can be seen here. Rail Grinding Traditionally, the rail head at Wiener Linien was ground as a five-sided polygon (see Figure 1). This approach has some negative impact on wheel wear, especially in …

Wheel Re-Profiling and Rail Grinding Strategies on Wiener Linien (Part 1 of 2)

January 4, 2014 | Filed under: Rail Grinding, Wheel Maintenance

By Edgar Fischmeister, Markus Ossberger, Roman Pongracz and Paul Mittermayr • October, 2007 Rail grinding and wheel re-profiling are essential elements of track and vehicle maintenance. These maintenance procedures have been shown to play a major role in the removal of surface defects or irregularities, and in controlling the shape and surface …

Using Wayside Load Detectors for Preventive Vehicle Maintenance (Part 2 of 2)

January 4, 2014 | Filed under: Measurement Systems, Vehicle/Track, Wheel Maintenance

By B. McGuire, R. Sarunac, R. B. Wiley and P. Klauser • April, 2007 Part 1 of this article examined ways in which the use of vehicle performance detectors is steadily growing on North American freight and high-speed passenger railways. With the installation of a Wayside Wheel/Rail Load Detector on …

Using Wayside Load Detectors for Preventive Vehicle Maintenance (Part 1 of 2)

January 4, 2014 | Filed under: Measurement Systems, Vehicle/Track, Wheel Maintenance

By B. McGuire, R. Sarunac, R. B. Wiley and P. Klauser • April, 2007 The use of vehicle performance detectors is steadily growing on North American freight and high-speed passenger railways. With the installation of a Wayside Wheel/Rail Load Detector (WRLD) on the Washington Metropolitan Area Transit Authority (WMATA), the trend …

Implementing an Anti-Shelling Wheel Profile

January 3, 2014 | Filed under: Wheel Maintenance, Wheel/Rail Profile

By Rob Caldwell • October, 2005 Wheel Shelling has presented serious problems on Canadian railroads in recent years, particularly in winter months. Tread shelling on wheels on Quebec Cartier Mining (QCM) railway’s heavy-haul fleet, for example, reached condemnable limits within one year of use, during the early 1990s. In some cases, …
