Re: Roller Coasters are amazingly designed!!!

Cedar Point is overrated. Their coasters, while many in number, are lackluster in performance. The only thing worth riding at Cedar Point, I think, is Magnum XL-200 (Airtime!).

If you want a really good coaster park with high caliber rides, Great Adventure, Busch Gardens Williamsburg, and Six Flags Worlds of Adventure can't be beat.

Nearly all roller coaster braking systems default to an 'activated' position if power is lost. This is usually achieved by a spring-loaded mechanism that brings the brakes into place, whether they be skid, pinch, or magnetic brakes. If you were riding a coaster with a midcourse brake run (MCBR), and power went out, the train would stop on the MCBR and you'd have to be evacuated from the train at that point.

PS
If anyone goes to SF Great Adventure, take a look at Batman and Robin, The Chiller, it is powered by linear induction, so what me and jason were thinking is, 'what would happen if the power went out while the car was gaining speed, (the roller coaster doesnt have a hill, it goes from 0-60 in like 2 seconds), but if the power went out, wouldnt the car not have enough power to finish the ride and get stuck somewhere, wheres the fail safe of that???


Shrey and Jason (Ulibrium)

The Chiller has a set of pinch brakes along the launch track that are closed immediately after the train is launched from the station. They open again when it returns, but act as a failsafe in case of a power outage or misfire.

Should the train gain enough momentum to complete the Tophat (on Batman) or Cobra Roll (on Robin), and there's no power for the Linear Induction Motors atop each spike to accelerate the trains backward, they will each come to a stop (after a lot of rocking) at the lowest point of the ride, which is located between the zero-g rolls and the tower.

That's called valleying. If though the train is launched, it still relies on its kinetic energy and all that jazz to complete the course.

Here again, you'd be evacuated from the train. However, to fix that problem, the train must be disassembled and moved via crane onto a truck, and then moved again via crane onto the storage track located behind the station.

This happens more often than you might expect.

As a final note; getting a job with a roller coaster manufacturer is exceptionally difficult. They're very, very small companies who usually employ no more than a dozen people of varying trades. Some of 'em are family run, too, which makes it even harded to get a job with them.

The big ones are:
Arrow Dynamics - currently in bankruptcy protection
Bolliger and Mabillard - of Monthey, Switzerland
Custom Coasters International - in Pa.
Giavanola - also of Switzerland
Vekoma - of the Netherlands
Intamin - of, erm, the Netherlands, I think.
Premier - of Maryland.
S&S - of Utah
Setpoint - also of Utah
Chance Morgan - of Wichita, Kansas, I think

There are other, smaller manufacturers, and many, many companies that manufacturer flat rides, as well. That's just a sample

Ian - Most roller coaster braking systems aren't magnetically driven. However, all Intamin coasters (Superman: Ride of Steel, Millennium Force, Xcelerator, California Screamin', etc.) are magnetically braked. Similarly, Intamin's drop rides (Drop Zone, Acrophobia, Giant Drop, Tower of Doom) all rely exclusively on permanent magnets as a powerless, failsafe braking system.
Nitro's computer system is very finicky. It loves to trip sensors for no good reason. The train stopping at the top of the lift is just to prevent block incursions, which are bad, bad, bad things Finally, consider yourself lucky for getting a ride on the Great American Scream Machine with the brakes off! Quit yet whinin'!!
