Mysterious Trim on SFNE B&M

Friday, February 1, 2002 10:46 AM
When I went to SFNE on Sunday I noticed a piece of track waiting to be placed that had a trim brake on it. The brake run is completely done so I don't know where it will be placed. Does anybody have any guesses? Do you think they had a speed issue with the track having only moderate elevation thru the majority of the ride? For photographic proof go to my site(see signature) and click on 2002 construction. You'll see it. BTW, the pic is on page 3:)

All B&M's are getting these of late.  Talon, NITRO, and BKF just to name a few.  I think they just install them to be on the safe side so that the company doesnt have to go back in and install the trims.  Didn't that situation happen on Montu?

All of the newer B&M's have trims at certain points.

Yep, this is common stuff.  Most are almost never on, too!

It helps when a park wants to control the ride time even more then with just brake-runs alone.

B&M is installing these to give greater precision to the control of G-forces at all times.  It allows them to design a coaster so that it isn't too much of a slug when cold, but doesn't generate G-forces higher than desired when hot.
The operation usually isn't very noticable since they are positioned at the bottom of hills, the proper location for trim brakes, not the tops as often seen.

Well, it's good to know that they don't want to make a ride that should be really intense tame.

From my understanding they are to help stop the train if a rollback occurs.  If you look at Talon their is one before the Immelman.  Notice the valley down there with the stair case leading down there.  Also on Batman Knight Flight there is one before the cobra roll, its never on but just like Talon there is a prox sensor so if a train rolls back through the trim will close.

And just how often do B&Ms roll back? Very rarely (Yes I know, Raptor is one of the biggest repeat offenders, no need to tell me that).

Actually Raptor isn't as bad.  As far as I know Raptor only rolled back in its opening year.

Riddler has rolled back a few times as well.  Its my understanding that those trims are ONLY for stopping a valey trains and NOT as a speed check.

Well, that's also good to know.
