Abstract
A locked-axle spring compression system and method configured to raise a rail vehicle wheel off a rail and transport the raised wheel along a rail is presented. In one embodiment, the present disclosure discloses a system that can raise the locked-axle rail wheel off the rail and allowing the locked-axle train to be transported off the main line. One or more coil springs can be disposed between the truck frame and the journal box to distribute the weight of the train and forces acting thereon. The present disclosure provides a technological solution missing from conventional systems by at least providing a platform for an actuator configured to exert a force on one or more train elements to compress the coil springs and allow the locked-axle wheel to be raised off a surface (e.g., railroad track rail), by overcoming the coil spring pressure to raise the wheel off the rail.
