I was under the impression that the "antirollback" on MF was going to be a set of permanent magnets that let the train roll backwards, but limited the speed. Given the sheer height of that hill, it would make sense to me -- if the cable broke when the train were 290 feet up, it'd kinda suck to get the patrons off ;)
And if that's the case, there's definitely not going to be any ratcheting sounds from the rollbacks ;)
