By Jeff Tuzik Friction modifiers—whether gage-face lubricants (greases) or top-of-rail (TOR) friction modifiers (FM)—are a well-established, and indeed, a common part of the wheel/rail optimization toolkit. In the railroader’s mind, these technologies tend to be associated with wayside application equipment and installations, but vehicle-mounted wheel-flange lubricators and wheel-tread friction modifiers …
by Jeff Tuzik In the railroad industry, friction management takes many forms. Managing friction through the application of lubrication and friction modifier products is a key component of maintaining an optimized wheel/rail interface. North American railroads typically use some combination of gage-face lubrication and top-of-rail (TOR) friction modifiers on various …
Friction management (FM) in railroads balances necessary traction and braking against wear and noise caused by steel-on-steel friction. Effective FM requires continuous management, as shown by studies illustrating significant benefits, including fuel savings and reduced rail wear. Challenges include maintenance logistics and aging equipment, necessitating trained personnel for optimal performance.
