The invention relates to a method for determining a position of a rail vehicle, moving on a track, by means of an optical measuring system comprising a stereo camera system and an evaluation device, wherein by means of the stereo camera system an image pair is recorded from a reference point in a lateral environment of the track and wherein by means of photogrammetry the position of the rail vehicle is determined in relation to the reference point. The position of the rail vehicle is additionally detected by means of a radio-based measuring system for real-time locating by means of anchor modules attached to the rail vehicle and by means of transponders attached to several reference points, wherein position data of the two measuring systems are compared by means of a central system unit. In this way, two independent measuring systems are used to generate position data.

Method and monitoring system for determining a position of a rail vehicle

A method for compaction of a track ballast bed uses a tamping unit including two oppositely positioned tamping tools which are actuated with vibrations and are lowered into the track ballast bed during a tamping operation and moved towards one another with a squeezing motion. A progression of a force acting upon the tamping tool over a path covered by the tamping tool is recorded during a vibration cycle by sensors disposed at the tamping unit for at least one tamping tool. At least one characteristic value is derived therefrom and used to carry out an evaluation of the tamping operation and/or of a quality of the track ballast bed. The tamping unit is thus used as a measuring apparatus during operative use. A device for performing the method is also provided.
