Vehicle guidance system that includes a first guidance bogie selectively positionable in a first position for travel and a second position for direction change and a second guidance bogie selectively positionable in a third position for travel and a fourth position for direction change. At a common crossing, one of: the first guidance bogie is selectively positioned into the second position, or the second guidance bogie is selectively positioned into the fourth position.

A bogie for a train vehicle includes two side frames, each side frame including two axle openings, each axle opening disposed on a corresponding end of the respective side frame, each side frame further forming a central slot disposed between the two axle openings; two wheelsets, each wheelset including an axle passing through two opposing axle openings between the two side frames; and a central beam having two ends, each end being slidably disposed within a corresponding central slot such that the central beam is disposed generally parallel to the axles of the two wheelsets and is slidable towards or away either of the two wheelsets.

A rail wheel set for a car which can be moved on a rail of a rail system has a bearing housing with a radial suspension for connecting the rail wheel set to the car, and two running wheels which are rotatably mounted on the bearing housing. Each wheel has a respective rail rolling surface, the shape of which is adapted to the contour of a running surface of the rail, and a respective ground rolling surface. The wheels can roll independently of each other on the running surface of the rail or on the ground. The rail wheel set is secured to a chassis of a car for transporting objects on a rail system.

A chassis for a rail vehicle includes a chassis frame supported on at least first and second wheelsets and one A-frame linkage per wheelset on both sides of the chassis for horizontal axle guidance of the wheelset. Each A-frame linkage is connected in an articulated manner to one of two axle bearings of a wheelset by a wheelset-side bearing and to the chassis frame by two frame-side bearings. At least one of the bearings per A-frame linkage has a hydraulic bushing with variable longitudinal rigidity. The hydraulic bushing has at least one fluid chamber fillable with hydraulic fluid so that in the fluid chamber a hydraulic pressure can form for adjusting longitudinal rigidity. An acceleration sensor per axle bearing measures wheelset acceleration and an adjustment device adjusts hydraulic pressure in at least one of the fluid chambers depending on the measured wheelset acceleration.
