👉 Rail fluid, also known as lubricating oil for rail systems, is a specialized lubricant designed to reduce friction and wear between the moving parts of railway tracks and rolling stock, such as wheels and rails. It is typically a synthetic or semi-synthetic oil formulated to withstand the harsh conditions of rail environments, including high temperatures, moisture, and abrasive particles. Rail fluid is applied to critical areas like rail joints, axle bearings, and wheel-rail interfaces to ensure smooth operation, enhance safety by minimizing derailments, and extend the lifespan of rail infrastructure. Its composition often includes additives to improve performance under extreme conditions, ensuring reliable and efficient rail transportation.
