Abstract: There is described a track travelling railroad switch tamping machine which has a transversally extending guide frame at its front end and four ballast tamping units one each mounted in individual sub-frames which are mounted on the guide frame. Hydraulic power means are provided to individually move each of the sub-frames with its tamping unit, transversally of the vehicle on the guide frames, independentally of each other sub-frame. Individual hydraulic power devices are provided on each sub-frame for individually raising and lowering each tamping unit within its own sub-frame, independently of the other tamping units.

Abstract: A golf cart system which can be installed on the fairway of a golf course and which is excellent in power economy and anti-overturn effect. The golf cart system includes a track embedded in the ground and a cart running on the track. According to the golf cart system, since the track width exposed at the ground is very narrow, there is little chance of a golf ball hitting against the track. Even if a golf ball should happen to accidentally hit the exposed track portion, the ball will bound similarly as when striking on natural grass if the exposed track portion is covered by elastic members such as artificial turf. This makes it possible to install the golf cart system on the fairway of a golf course. In addition, since the anti-overturn rollers are so arranged that they elastically press onto the side walls of the track, the load acting between the driving wheels and the track is only the dead weight of the cart itself and therefore no excessive frictional force acts therebetween.
