"working" overhead line
So I had part 27965 originally in mind to replace the strings for my tank wagon. As it looked a bit more versatile I got 4 more and immediately had the idea of using them for overhead lines. They are of a softer material than normal Lego bricks which makes it very comfortable.
As you might see the current collector not only touches the line but also pushes it a little bit up. So far it works very well and I'm sure it would withstand a longer period of testing. I hope this might be an inspiration to some to finally get in our time and electrify their lines :)
