Abstract
A railway locomotive has three power trucks with the end trucks each having a bolster resiliently supported on the truck frame and connected to the underframe by cooperating vertical axis pivot-forming means, the middle truck bolster being connected to the underframe by a Watts linkage arranged to directly transmit longitudinal forces from the bolster to the underframe while accommodating substantial excursions of the bolster and middle truck frame transversely of the locomotive underframe for operation of the locomotive on the curved track. To prevent substantial axle-to-axle load transference on each of the trucks, each of the bolsters supports the locomotive underframe by opposed sliding surfaces spaced apart a substantial distance lengthwise of the locomotive and each of the bolsters is connected to the respective truck frame by traction transmitting means constructed to transmit the longitudinal traction forces from the truck frame to the bolster and thence to the underframe effectively substantially at rail level.
