Abstract
Embodiments of innovative designs and use of switch rods are disclosed. In one particular embodiment, a method of preventing derailment of a train traveling through a previously run-through railroad switch may include installing a railroad switch rod assembly to couple a switch point of a railroad switch with a railroad switch stand. The method may also include configuring a locking mechanism in the railroad switch rod assembly such that, upon a railway vehicle trailing the railroad switch in a first direction, the locking mechanism maintains the railroad switch in a condition that accommodates safe movement of the railway vehicle through the railroad switch in a second direction opposite to the first direction.
