What are these wires for?

These wires are for the grounding of the train tracks. Everything that is made out of Steel or Metal in general needs a or multiple grounding wires so when a lightning hits the tracks the electricity gets safely transported into the ground reducing any damage on humans, animals and the infrastructure.

Those are most likely for train detection via track circuits which enable operations to know the approximate location of trains for signalling and also can alert of a derail or stopped train, though now with GPS it's probably used less which may be why those cables look in rough shape in a couple spots.

 

I don't think they're grounding cables for several reasons, why so long? why not just ground right next to the rail? why ground the rail at all, it's laying on the ground and lightning would just jump right to the ground.
