摘要： A suspension system for a train vehicle includes at least one inerter to minimize track wear. Track wear may be measured by direct measures such as wear work, or indirect measures such as yaw stiffness. “Minimizing” track wear means that such measures are reduced below values which are achievable with conventional technology while maintaining acceptable values of other performance metrics, such as ride comfort or least damping ratio. The suspension system may comprise at least one damper connected in series with the at least one inerter. The suspension system may be the primary or the secondary suspension system of a train vehicle.

摘要： A railway points arrangement 10 for a railway track junction comprises at least first and second pairs of longitudinally-extending, parallel-spaced static stock rails 12, 14, defining respectively a first route and a second route, and a pair of longitudinally-extending, parallel-spaced switch rails 16 which are movable between a first position in alignment with the first pair of stock rails 12 to select the first route and a second position in alignment with the second pair of stock rails 14 to select the second route. At least one of the movable switch rails 16a cooperates with at least one stock rail 12, 14 of each of the first and second pairs of stock rails 12, 14 when the movable switch rails 16 are in the first and second positions, and the at least one switch rail 16 and the at least one stock rail 12, 14 are shaped to define a mating profile 50 which aligns the switch rail 16 and stock rail 12, 14 and prevents transverse movement of the switch rail 16 relative to the stock rail 12, 14.
