Electricity from Railway Tracks
Electricity from Railway Tracks
(OP)
A couple of days ago, I saw this video (https://youtu.be/oeYVjOdkUEc) and thought of the source of energy. Is it from nearby high-voltage power line induction or traction of the train itself causes this differential potential energy.
I've heard from one of my colleagues that some years ago a poor electrician died when touching two cables which were cut from main line, due to voltage which was inducted from nearby high voltage power line.

How do you think the crossing lights know there is a train?

Half full - Half empty? I don't mind. It's what in it that counts.

But as you see from the youtube link, the voltage is very changing (when the loudspeaker is connected) and does not correspond to a predetermined applied one.

Honestly, I've seen more induced voltage from a car parked in a substation.

Most likely part of the signalling system.

Incidental effect of this new strategy is that you lose the ability (admittedly a bit hit and miss with track circuits anyway) to detect obstructions that just arrive in the middle of the section, rather than rolling in from the end.

I believe the interblock communications is like the power line carrier used in the power industry. And with that some of the signal will migrate from one rail to the other.
