Patent ID: 7730840

Claim:
A track carrier for a railborne vehicle, comprising: a carrier with a concrete plate having lateral ends extending from a web, with stator components attached at bottom surfaces of said lateral ends, guide rails attached to outward lateral sides of said lateral ends, and vehicle glide strips configured on a top surface of said concrete plate; a plurality of spaced apart hardened concrete contact surfaces formed directly in the material of said concrete plate along said outward lateral sides of said lateral ends, said contact surfaces extending outwardly from an outward surface of said outward lateral sides and defining uniquely shaped and located points for detachable attachment of said lateral guide rails such that a space is defined between said lateral guide rails and said outward surface of said outward lateral sides between said contact surfaces; and said contact surfaces having an outwardly extending dimension with respect to said outward surface of said outward lateral sides such that an exact overall tolerance for said guide rails that are subsequently attached to said contact surfaces is achieved with respect to said outward lateral sides.
