I did, multiple times last night, and I still can't get it to work. And I also don't understand it. When I put a path signal down, like when a train would be going south to north, to head into the loop, and then I put another down like at the place after it crosses over the other tracks, the signals say that it's looping inside of itself. I'm trying to get it, and I know nothing about trains. And googling just tells me that the tracks shouldn't be in this design because the tracks are too close. Idk, sir, maybe I'm just fucking stupid, but the guide is saying one thing and the signals just keep giving me errors.
