Abstract
A rail assembly for use with a bogie wheel includes two rail segments having mating end segments abutting against each other, and joined by a connecting bolt that traverse the mating end segments. A bogie for use with a rail includes a support frame, a chassis movably attached to the support frame, and an elastomeric bearing disposed between and in bearing engagement with the support frame and the chassis, to limit movement of the chassis relative to the support frame. A bogie wheel includes a central hub adapted for direct mounting to a bogie chassis, a tread, and a bearing assembly permitting rotation of the tread relative to the hub. An inflatable seal assembly for sealing between a first member and a second member includes an inflatable bladder, a membrane attached to the first member, and a tension spring attached to the membrane to bias the membrane against the bladder.
