This wont make sense to many people but I am just looking at TT2 now as a high performance race car. If you want to go fast or do cool things you just know things will break. On a race car a motor might blow, suspension might go out you kind of don't want it to happen but know it will at some point. you rebuild and repeat. Like most roller coaster track parts get welded. TT2 might just have times that it closes for a few days to repair/ a part weld a crack and they might have replace said support pole ever year ever other year. They just become wear items just like the old cable was.
