Whitmore TOR Armor Biodegradable Top-of-Rail Friction Modifier

What is TOR Armor Biodegradable Top-of-Rail Friction Modifier?

TOR Armor® is a revolutionary water-based bio-lubricant consisting of water, plant-based oil, and other additives. This top-of-rail friction modifier is specifically designed to provide a friction coefficient between 0.3 and 0.4 at the wheel-rail interface. TOR Armor substantially reduces noise, wear, and lateral forces. High lateral forces lead to loosened tie plates and fasteners, and can result in low rail rollover. During normal rolling, TOR Armor acts as a lubricant. But when wheel creep occurs the sliding friction immediately converts to “positive friction”, controlling the creep condition and returning the wheels to a healthy rolling motion. The result is a substantial reduction of vibrations, corrugations and high-frequency squealing.

The positive friction generated by TOR Armor reduces lateral creep, thus reducing lateral forces. This has been measured on instrumented track at TTCI and Class 1 and 2 railways. TOR Armor offers a year-round solution by using regular TOR Armor in hot to moderate climates and adding TOR Armor Artic in areas where temperatures dip below 10°F (-12°C) for extended periods of time. Both grades of TOR Armor are fully compatible and can be mixed in trackside applicators without changes to the performance characteristics other than the low temperature usage.
