Abstract:

A magnetic skirt assembly is provided which is used as a metallic particle and grit collector on a railroad car to protect transported products. The magnetic skirt (20) includes a supporting frame structure (21) and a magnetic material (36) operatively attached thereto. The magnetic skirt is installed on the underside of the railroad car, preferably one skirt at each end of the railroad car adjacent to the outboard side of the wheel trucks. The magnetic skirts of the invention attract and collect fine metallic particles and grit on their magnetic surfaces which come off the railroad bed during transit of the railroad car. The design of the magnetic skirt particularly addresses the primary flow of air through the railroad car wheel trucks directed outboard and the airstream carrying the metallic particles flowing upward between rail cars which can potentially enter the gaps in the railroad car end doors. Periodically, the magnetic skirts can be cleaned or rinsed off to remove the accumulated grit or particles.
