Patent number: 7484669Abstract: A rail cover and support for mounting and insulating the rails of an electric transit system in which the rail cover is vulcanized both to the rail and outer skid support at the manufacturing site prior to delivery to the field and a rail cover completely surrounds both the base flange and web portion of each rail and terminates along the undersides of the top flange. In one form, the upper free ends of the rail cover are increased in thickness to form bumpers along opposite sides of the rail to cushion it against undue shifting or vibration. In fabricating the rail, a sheet dielectric material is vulcanized to the rail with or without a skid plate.Type: GrantFiled: April 5, 2005Date of Patent: February 3, 2009Assignee: MetroShield LLCInventor: Harold W. Gray, Jr.
