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.

First claim

The invention claimed is:

1. A method for a mixed operation of a track-bound line section, which comprises the steps of:
traversing the track-bound line section with trains equipped with a train protection system, and by trains not equipped with the train protection system; and
fitting the track-bound line section with at least one switch, in an event that a train that is not equipped with the train protection system is to enter the track-bound line section, a block section of the track-bound line section which extends as far as the switch is authorized, wherein the switch is set for a purpose of following-move protection and the switch is reset again before a passage of the train that is not equipped with the train protection system.

2. The method according to claim 1 , which further comprises providing a plurality of switches in the track-bound line section and a block section extending from one switch to a following switch is authorized, wherein the following switch is set for a purpose of following-move protection and the following switch is reset again before a passage of the train that is not equipped with the train protection system.

3. The method according to claim 1 , wherein in an event that the train that is not equipped with the train protection system is to enter the track-bound line section, the switch is set for a purpose of following-move protection only if the train is situated in the block section which comes after the switch or a train enters the block section which comes after the switch during a time in which the train that is not equipped with the train protection system is expected to be situated in the block section extending as far as the switch.

4. The method according to claim 1 , wherein the block section is authorized for operation of the train protection system again as soon as the train that is not equipped with the train protection system has left the track-bound line section again.

5. The method according to claim 4 , wherein the block section is authorized for operation of the train protection system again only if a track clearing run has first been performed on a respective track section by a train that is suitable for operation with the train protection system.

6. The method according to claim 1 , wherein for a purpose of operating the train that is not equipped with the train protection system, a communication interface between a train driver of the train that is not equipped with the train protection system and a lineside train protection configuration is used.

7. The method according to claim 1 , wherein for a purpose of operating the train that is not equipped with the train protection system, line-based detection is performed.

8. The method according to claim 1 , wherein a first lineside train protection configuration, which controls the track-bound line section, communicates with a second lineside train protection configuration, which controls a further line section coming after the switch.

9. The method according to claim 8 , wherein the first lineside train protection configuration sets the switch only if an authorization of the further line section is granted by the second lineside train protection configuration.

10. The method according to claim 1 , wherein for a purpose of operating the train that is not equipped with the train protection system, line-based detection is performed by means of axle counters.

11. The method according to claim 1 , wherein the train protection system is a communication-based train controller (CBTC).

12. A track-bound line section to be traversed by trains, the track-bound line section comprising:
at least one switch, in an event that a train about to traverse the track bound line section and is not equipped with a train protection system enters the track-bound line section, a block section of the track-bound line section which extends as far as said at least one switch is authorized, wherein said at least one switch can be set for a purpose of following-move protection and said at least one switch can be reset again before a passage of the train that is not equipped with the train protection system.

13. The track-bound line section according to claim 12 , further comprising a lineside train protection configuration which controls the track-bound line section and allows said at least one switch to be set in accordance with conditions stated in claim 11 .

14. The track-bound line section according to claim 12 , wherein no light signals are provided at said at least one switch.

15. The track-bound line section according to claim 12 , further comprising a light signal disposed only at a beginning of the track-bound line section, as viewed in a direction of travel.
