Patent

CA 2349315

A support structure for an elevated railway, for example an elevated linear induction motor (LIM) railway, includes separately formed open U-shaped support girders and multiple guideway slab elements made of reinforced concrete. The girders are typically pre-formed and then assembled atop of appropriate supporting columns before the guideway slab elements are individually mounted and aligned atop the girders. For an LIM railway, the top surface of the guideway slabs includes pre-formed lateral canted rail support surfaces and a raised central LIM rail support to facilitate the use of economical fittings to attach the carriage rails and LIM rail to the guideway, and integrally formed lateral parapets to provide derailment protection. A mold design and mold support apparatus are provided for forming the guideway slabs from reinforced concrete wherein the mold support apparatus facilitates support of the mold in casting and resting positions.
