It's not a problem in Japan because the temperature range isn't as extreme. And all it takes is a couple of degrees to make the problem go away.Oh, I know why it happens (but thank you for the explanation anyways), just wondered why we can't use expansion joints or something else so we don't have to worry about this. Lived in Japan for a bit & they get hotter than here (albeit not as cold), and they don't have this issue, so I thought it might be solvable, but it seems after ready all the comments likely not.![]()
The railways here do use expansion joints. For instance, most switches are not welded in, they're bolted in for specifically those reasons. But because of the temperature swings the rate of expansion and contraction is still so substantial as to make it a problem here.
