Abstract: A switch or rail box for railway rails that include a system for sealing a portion of a location where the rail enters or exits the box. The sealing system includes a pair of seal plates that can be connected to an inner surface and an outer surface of the switch box, wherein the sealing plates each include a groove that conforms to and accepts a portion of a rail and in some embodiments, a rail jacket. The channel formed between the adjacent seal plates is filled with an insulating material that extends around a lower portion of the rail, thereby aiding in stray current control. Methods for sealing the switch box utilizing the sealing system are disclosed.
