  • Patent number: 11850529
    Abstract: An indoor zip coaster has a zip coaster rail suspended above ground and forming a closed loop. At least one trolley located is on the rail, with a rider tethered to the trolley by a harness. The rail has plural sections, with each section of the rail including an incline portion and a decline portion. The trolley traverses the respective incline portion of one of the sections before traversing the respective decline portion of the one section. Each of the stations contains a respective incline portion of rail, a ramp for the rider to climb. The decline portion of rail of the next section extends from one station to the next station. By including stations with inclined portions of rail along the zip coaster path, a longer ride can be obtained.

  • Patent number: 11834084
    Abstract: In a method for mixed operation of a section of railroad line, the section of line is trafficable by trains equipped with a train control system, and by trains not equipped with this train control system. The section of line is provided with a switch so that in the event that a train not equipped with the train control system is to enter the section of line from the direction of a side track, the section of line is indicated as occupied. The occupied indication is triggered by a first throwing of the switch in the direction of the side track. After the train not equipped with the train control system has passed through, the occupied indication is canceled. The cancelation is triggered by a second throwing of the switch. After throwing of the switch, a clearing run is carried out on the section of line by an equipped train.

  • Patent number: 11821147
    Abstract: 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.
