What are methods of making a track inaccessible on non-controlled track?

Making a track inaccessible on non-controlled track primarily involves implementing physical barriers that ensure safety and prevent unauthorized access. A switch or derail works effectively by redirecting trains to a different track or derailing them, thereby preventing any movement onto the inaccessible track. This method is widely recognized in railroad operations as a critical approach to maintain safety and control over train movements, especially in work zones where workers are present.

Temporary safety barriers, while useful, do not necessarily provide the same level of control over train movements as a switch or derail. Marking areas with cones or hiring security guards may help to deter people from entering a designated area but do not offer a physical means to prevent train access. Therefore, the use of a switch or derail directly impacts track accessibility, making it the correct approach for achieving the objective of making a track inaccessible on non-controlled track.
