A method for compensating for a loss of traction of a rail vehicle, preferably a freight locomotive, in a track curve, is particularly pertinent when the rail vehicle is starting up and/or is on an incline. Comparably unfavorable frictional conditions between a track and at least one driven track wheel of the rail vehicle are changed into comparably favorable frictional conditions by actively steering the track wheel on the rail. 110-. (canceled)11. A method for compensating for a loss of traction of a rail vehicle , the method comprising:changing comparatively unfavorable friction conditions between a rail and at least one driven track wheel of the rail vehicle into comparatively favorable friction conditions by actively steering the at least one track wheel of the rail vehicle on the rail.12. The compensation method according to claim 11 , wherein the rail vehicle is a freight locomotive.13. The compensation method according to claim 11 , which comprises effecting the changing step while starting up the rail vehicle or while driving the rail vehicle on an incline.14. The compensation method according to claim 11 , which comprises effecting the changing step in a track curve of the track.15. The compensation method according to claim 14 , wherein:the driven track wheel is a constituent part of at least one driven wheelset of the rail vehicle; andthe step of changing the comparatively unfavorable friction conditions between the track curve and the at least one driven wheelset into comparatively favorable friction conditions comprises actively steering the at least one wheelset on the track curve.16. The compensation method according to claim 15 , which comprises compensating by subjecting the at least one wheelset to at least one of the following:actively steering hydraulically, pneumatically, mechanically, electrically, and/or electromechanically;adjusted axially and/or radially; and/orpivoting about a pivot center.17. The compensation method according to claim 11 ...

A bolster system and method of balancing a locomotive on a bolster system is provided. The bolster system is configured such that weld seams interconnect the locomotive to the bolster, and the weld seams are oriented such that when the truck or locomotive impacts another device on the rail track, the weld seams experience a shearing force along the lengths of the weld seams. In addition, prior to welding, scales such as hydraulic jacks with gauges may be used to center and balance a locomotive on a bolster. In one embodiment, four hydraulic jacks elevate the truck, bolster, and locomotive, and the locomotive is repositioned on the bolster until the hydraulic jacks have substantially similar measures. 1. A bolster system for a locomotive , comprising:a truck configured to travel along a rail, the truck having an axle with a rotation axis and the truck having at least one suspension device with a suspension axis, wherein the suspension axis is substantially perpendicular to the rotation axis;a bolster interconnected to the at least one suspension device such that the bolster moves relative to the truck along the suspension axis;a first underframe plate and a second underframe plate of the bolster, wherein the underframe plates define an upper surface of the bolster; anda locomotive body interconnected to the bolster, wherein a first weld seam interconnects the locomotive body to the first underframe plate, and a second weld seam interconnects the locomotive body to the second underframe plate, and wherein the weld seams are oriented substantially perpendicular to the rotation axis of the axle of the truck and substantially perpendicular to the suspension axis of the at least one suspension device.2. The bolster system of claim 1 , wherein the first underframe plate has a longitudinal dimension that is substantially perpendicular to the rotation axis of the axle of the truck and substantially perpendicular to the suspension axis of the at least one suspension device.3. ...
