Neat Video on Electric Train Power Lines

Jul 2, 2022

YouTube recommended the following video to me tonight. It answers a number of questions I've always had about how the power lines for electric trains are structured:

  • How is the contact wire kept straight?
  • How does it deal with temperature variations?
  • Why do the electric lines have so many components?

The animations in this video make it all clear. It's well worth the short watch if you're curious about this stuff like I am.
