Sometimes when you do a search on a topic you get distracted with something completely different.
I had to wonder, what is an "anti-theft device" for railway tracks ? I think something got scrambled in the translation and it really means "anti-creep" device. It looks like these gadgets lock the rails to the crossties, like rail anchors but more complicated with more pieces.
There are some other curious railway items on this website.

A device for fastening the way from theft /A. with. USSR N 1414909, E 01 B 29/24, 1986/, containing fixed on the top of the bed sleepers sleeper protivopo in contact with its side surface, opposite to the direction of traffic, and rail protivopo installed in the direction of movement, which provides improved reliability of the mounting path on steep slopes by increasing the resistance to longitudinal shear rail and tie bars on sections of the route with known direction of action of the forces of theft.

However, the operation of the quarry Railways is the unpredictability of the direction of forces theft, because on any section of the road at any time can take place as the acceleration of the rolling stock and its inhibition, which changes significantly as the magnitude and direction of forces theft, as well as significantly increase efforts Rusanovka sleepers, destroying rail fasteners.
