I was just wondering, what B&M's have valleyed? I believe that Mantis has, but are there any others? For the ones that have valleyed, where in the ride, when, and why did they valley (if you know)? I was just asking this out of my own curiosity. Thanks
1: Going into the first loop, made it till the mid point of the loop, then rolling back....
2:At the end, after the corkscrew, as you the the "batwing" turn (dont know if thats the right term, our whole crew just called it that). This rollback only occurs in the early am when we are doing block checks.
3: See #2, and repeat a couple of times!
It seems to really depend on weather for her to rollback. Mainly dependent on if its really cold (I believe under 45F and the track tends to seize, though i could be wrong) and if the wind kicks up hard core, but I dont think we've had her roll back loaded?! (anyone know for sure?)
The worst issue we had was when we lost complete power for the whole park two years ago. We had train #2 stuck 3/4 of the way out of the main brake run (where your @ a nice angled turn *over the freaky green water* into the safety brakes) Unloading guests there was an adventure to say the least)!
I believe cell block tango means Mantis, not Maggie. Anyways, do you know where Raptor and Batman valleyed?, I heard the GADV Batman valleyed as well, but that just doesn't seem logical because the trains travel so quickly through the course.
Medusa at SFMW has not had a problem with vallying at all, and the brake before the sea serpant (could hold the train in place while they unload it) was removed for the 2002 season. That brake could also be used as a trim, but never was... but on a side note I did notice how incredibly slow Mantis's morning runs are.
As they said above, Mantis, Raptor, and Riddler's Revenge have rolled back. Raptor rolls back on the helix before the midcourse brakes. That's why they don't run it when it's windy. I've been on it when it crawled through the brake run. It was pretty scary.
I only know of Riddler rolling back once, but it's done it many times, for sure. I know it rolled back between the two dive loops.
Batman is the only ride at SFMM that has never rolled back, I'm told.
I'm sure Chang's rolled back, since it's practically Mantis. But it doesn't have that trim brake.
Soggy the difference between B&M and lets say Vekoma or Premier (specially B&R:TC) is that their hasn't been an rollback that was loaded (that I know of at lease). Additionally if any B&M did roll back loaded I am sure that none would stall upside-down (ALA SFMW’s Boomerang or Robin in the heart-line roll)
So Medusa at SFMW, never runs three trains? If so that's a shame but not surprising. When I was there in March, two were running but the third was on the transfer with no wheels. I was assuming for maintinance. I don't think a B&M would stall upside down either, they are just designed too well. The only B&M I've been on that I could see valleying is possibly Talon because it seemed slow in the loop and immelman.
Antuan said: Goliathkills, the MCBR is after the Sea Serpent, and although they have a permanent two train operation, it still grabs (why, I have no clue)!
Yes, the MCBR is still on, but there is a small single brake that is right after the heartline camelback... here is a picture. After asking a couple of people, it isn't for rollbacks, it's just a trim. Still, it's great that it was removed, nothing is worse than a trim (especially at a time like that.)

SFGAdv's Batman rolled back this spring on the same day as Chiller. It was the 2nd day of the season. Saw the aftermath of both with my own eyes. It was really, really cold that day and Nitro and Medusa almost didn't make it a few times. *** Edited 11/21/2003 3:46:11 AM UTC by Michael Darling***
The beemers in MO have yet to catch Wal*Mart Fever™ -Swoosh. (EDITED TO REMOVE OFFENSIVE MATERIAL THAT MADE VolcanoTBC UPSET IN ANOTHER THREAD, SORRY TO HAVE TO SENSOR MYSELF) -- though, we only have two. (Wildfire and namtaB).
It was a cold/windy day last year in August, they were running the final empty cycle before closing the ride for the night. The evil trims slowed the train way too much, it barely crawled out of the Bat Wing, and didn't come close to getting up the MCB. Took 10 - 15 minutes to stop rollign back and forth, funny as hell to see! :)
