Trains in Switzerland Are Now Running Over Solar Panels in a First-of-Its-Kind Test

We could use the railing to transmit power but nah we have to use it to house power source

That’s already the standard in Switzerland. The overhead line is the phase and the rails are ground.

Oh like trans? They have those overhead lines they use as third rail

In what world is it reasonable to put a several kilovolt line on the ground? Even subways have safety problems with the third rail.

Damn you want kilovolt? I was thinking few hundred at most. Over a few miles it would be fine to power like lights and low powered devices

There is usually a current present in the rails already

Either traction current, signalling current for track circuits, or both

Depending on the way the signalling system has been engineered

Hmmm neat. I guess those are high voltage signals

FistingEnthusiast@lemmy.world · 1 天前

Definitely not

Sometimes in the order of mere milivolts
