Quoted from mbeardsley:Don't know about the locking, but for the subway I shaved off a bit on the left side, just enough to make the opening a bit larger. It took a couple of tries, but it wasn't hard. Best thing to do is with the playfield lowered into position, look through the coin door with a flashlight to see exactly where the ball is stuck.
Yeah alnost seems like it gets stuck where I can't see it , like way left ? Definitely not all the time .
