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.

Abstract: A method performs a mixed operation of a track-bound line section. Trains that are equipped with a train protection system run there. In order to guide trains that are not equipped with the train protection system through the line section, provision is made for switches to be set as a protecting switch for the purpose of following-move protection. However, the switch is reset again before the passage of the unequipped train, wherein the respective block section of the line section must be free again at this time point. The method therefore allows mixed operation of equipped and unequipped trains while at the same time requiring limited component expense for lineside train protection apparatus.

Abstract: A device for infrastructure-side monitoring of a position of a stabled rail-based vehicle includes a detector for infrastructure-side detection of a change of location of the stabled vehicle and a communications entity or device configured to communicate the detected change in location over a communications network to a user of the communications network. A corresponding method, a corresponding system, a method for operating the system and a computer program product are also provided.
