When you can't manage to bring the tracks together and there is just a little angle mismatch.. Instead of trying to force the two rails together and potentially break them use one of these.
The 75° and 60° ones are a life saver. I made more with a stronger bend (I don't know about those ones, but there you have it)
Update 1: I added another angle 82°, quite useful. It's not on any of the renders, but you get the idea.
