Canada's Wonderland Discussion Thread

^That is bizarre. It kind of defeats the purpose of being able to control the speed of the train (based on weight, wind, etc...)

 

Unless they are adjustable?

I'm guessing B&M already knows it's going to be going too fast for their comfort at that particular point. We'll have to wait and see if the next trim is mechanical since that would be a more appropriate place to use one. Things could change by the time the ride opens though, issues can be found during testing.

 

It might also be because they didn't want people hearing a mechanical brake catching the train every time the people at the front gate watch the train go over that hill. We all know how unattractive Time Warp sounds.

I'm sure that the magnetic brakes are adjustable, not so much on the fly like mechanical brakes. Remember how many revisions the trims on the first drop on i305 went through that opening season. As I recall they make the fins out of different materials that control how powerful the brakes are.

I don't get it. Why engineer a portion of a ride knowing that it'll need a trim? Why not just engineer it a little differently so it doesn't need it? Then again, I've never designed a roller coaster before, so I'm a little ignorant in the ways of the engineering, but it seems silly to design a coaster with trims rather than try to make the layout so that it doesn't need them.

I don't know either but maybe it has to do with the variations you could get in the speed because of weather and weight of the train. If you made an element that could be taken at any speed the ride might produce than you might have a pretty blah ride.

One guess would be that if there weren't no trim, the hill would be higher to manage the speed. Knowing B&M, they would stretch it out instead of having a pointier apex, so then it may not meet the footprint limitations. Then there's also the cost of making a bigger hill vs the reduced cost of having parts last longer if they can run it at a slower speed.

 

Does B&M have any existing adjustable magnetic brakes, either on trims or brake runs?

They're magnetic trims. There's a pneumatic actuator that can slide one of the reactor plates back and forth to adjust braking force.

Image below shows the brake assembly plus pneumatic actuator directly below. The assembly shown in image is part of Intimidator's main brake and not a trim however B&M seems to have implemented this same design for a trim brake on Leviathan. Obviously fully loaded trains will get more braking force than an empty train.

This type of trim brake makes no physical contact with the train thus reducing wear and providing a smoother ride for the riders.
