Abstract
A rail tie has a pair of rail supporting portions disposed on opposite sides of a central portion. The central portion is elevated relative to the central portion and supports a reaction rail of a linear induction motor used to propel a vehicle along the guideway. The reaction rail is secured to flanges extending laterally from the central portion to reduce the unsupported span of the reaction rail between ties. The tie is supported on the deck of the guideway by resilient pads. An eccentric insert cooperates with a securing stud to allow alignment of the tie.
Claims24
A rail tie comprising an elongate body having a central portion and a pair of rail supporting portions located on opposite sides of said central portion, each of said rail supporting portions including an upwardly directed rail support pad to receive a rail, said central portion being elevated relative to said pad and including a pair of flanges projecting laterally outwardly from opposite sides of said central portion at a location above said pads to provide a support for a reaction rail extending between adjacent ties.
A guideway for a rail vehicle comprising a deck, a plurality of ties spaced apart generally parallel to one another transverse to the direction of movement of the vehicle along said guideway, each of said ties having a central portion and a pair of rail supporting portions located on opposite sides of said central portion, each of said rail supporting portions including an upwardly directed rail support pad with said central portion being elevated relative to said pads, said rail support pads being inwardly canted toward said central portion to provide a neck between said pads and said central portion, fastening means to secure each of said ties to said deck and including an anchor extending through an aperture formed in said neck and secured to said deck, a pair of rails, one supported on each of said pads, extending between the ties in said direction of movement and a reaction rail supported by and extending between said central portions of adjacent ties generally parallel to said rails.
A rail tie comprising an elongate body having a central portion and a pair of rail supporting portions disposed on opposite sides of said central portion, each of said rail supporting portions including an upwardly directed rail support pad to receive a rail, an aperture extending through said tie adjacent each of said rail support pads to receive a fastener to secure said tie to a deck and an insert located in each of said apertures, each of said inserts having a hole therethrough disposed eccentric to said aperture whereby rotation of said insert in said aperture varies the position of said hole.
