MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517029196 A) filed by Bnsf Railway Company, Fort Worth, U.S.A., on March 27, for 'locked-axle spring compression system and method.'
Inventor(s) include Schafer, Henry, R.; Teaford, Mike; Romero, Christopher, M.; Meyers, Edward, M; Webb, Timothy; Kimberlin, Ryan, L.; and Valentine, Larry, C.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "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 (110) off the rail and allowing the locked-axle train to be transported off the main line. One or more coil springs (104) can be disposed between the truck frame (702) and the journal box (102) 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 (104) and allow the locked-axle wheel (110) to be raised off a surface (e.g., railroad track rail), by overcoming the coil spring pressure to raise the wheel off the rail."
The patent application was internationally filed on July 18, 2023, under International application No.PCT/US2023/070405.
