Come fa la catenaria ferroviaria a rimanere tesa

Those who have been using our site for years know that we cover a variety of topics, all in a simple way so everyone can understand them, while always maintaining the accuracy of the information, which is taken from official sources and not from alternative sources like those sites that pretend to be science and truth disseminators. For Science Cheat Sheets today, we'll look at "How does a railway catenary stay taut?" Why isn't a simple cable enough, and what are all those cables and weights we can see when we look up? As always, let's explain everything simply and briefly. We created this video about trains based on the great interest we saw in another video about how train wheels turn even without a differential. If you missed it, you can find it on our channel by browsing the videos. If you support us, we'll improve the quality of our videos and graphics.
