Glossary of Terms

What are coaster/theme park enthusiasts talking about? What does something mean? This might clarify at least some of it. Common acronyms, sayings, and more.


Airtime: It is simply when you go into Negative-G's on a ride. You are lifted out of your seat. "Floater airtime" is seen on B&M's (Negative G's just under 0.0g) and "Ejector air" is seen on Intamin's and RMC's (More Negative G's, -0.6 and approaching -2.0 in today's coasters)


Arrow: Arrow Dynamics was arguably the company that did the most for the Roller Coaster industry, Arrow were pioneers until their operations ceased in 2002, they were taken over by S&S Worldwide.

B&M: Bolliger and Mabillard, they create some of the smoothest coasters of today. Hypers, Drop Coasters, and Inverted Coasters are what you are most likely to associated this company with.

Blocking/Block Brake: When a coaster car clears a lift hill or brake run, the train behind it is allowed to move forward with its run until it comes to the same block brake. This makes it so trains can never collide. This system was manually disengaged by employees during the Smiler's famous collision.


E-Ticket Attraction: An attraction with the latest technology or highest popularity. The term comes from the admission ticket system used at the Disneyland and Magic Kingdom parks before 1982. An E-ticket would allow the guest entry to one of these attractions.

Giga: A coaster that is over 300 feet tall, and under 400 feet tall. See "Strata" for over 400.

Gravity Group LLC: Known for their steel supported wooden coasters, Gravity Group makes some of the most unique coasters you'll find. Never scared to take on a task no matter what the plot of land they're given. The team of engineers at The Gravity Group has more experience designing wooden roller coasters than any other company in existence today. 

Hybrid: Combines two building materials. For example, a roller coaster with steel supports and wooden track (Invadr at Busch Gardens), or wooden supports and steel track (New Texas Giant at Six Flags). The class of coaster is usually determined by its track type (NTG is steel, Invadr is Wood).

Hyper: A coaster type that is over 200 feet tall, but under 300. See also "Mega." See "Giga" for over 300.

Intamin: Intamin Worldwide makes some of the best coasters and rides in the world. You'll mostly associate them with Hyper Coasters like Superman:Ride of Steel or Goliath at Walibi, and Strata-coasters like Kingda Ka/Top Thrill Dragster. They also make great Log Flumes.

Lats (Lateral G's)- Lats are usually used as an asset on wooden coasters. It gives you an out of control feeling that also makes the ride seem faster. They're usually uncomfortable with Over the Shoulder Restraints, so you won't usually feel them as much on coasters with the over shoulder restraints.

LIM: Launch System, Linear Induction Motor. Induced magnetic field is used to launch the coaster.

LROTNOB: (el-rot-knob) Last Ride of the Night on Beast.  Kings Island crazies always try to get the last ride on Beast at night, as the track is warmed up most (fastest) and the ride is the darkest. The best ride all day is the LROTNOB.

LSM: Launch System, Linear Synchronous Motor. The motor has a fixed magnetic field to launch the coaster.

MCBR: Mid Course Brake Run, the Brake in the middle of a coaster that is there for blocking purposes.

Train travels into the MCBR on Hollywood Rockit at Universal Orlando.
Mega Coaster: A coaster with a drop or height above 200 feet. See also "Hyper."

OTSR's: Over-The-Shoulder-Restraints. Used on many steel coasters, the restraints that pull down over your shoulder. Rides like HULK and Nemesis use OTSR's.


RMC, Rocky Mountain Construction: One of the newer coaster companies that recently blew up in popularity, they are designing and opening multiple coasters a year all with very high ratings. In a category of their own, their transformations of old wooden coasters and out-of-the-box elements make their coasters a favorite among many riders. 

Rolling Thunder Hill: This is the last airhill on El Toro, right before it heads into the twister section. It is known as Rolling Thunder Hill because when El Toro was constructed, this airhill went over the Rolling Thunder wooden coaster.


S&S: Sansei Technologies, moving the industry forward with new designs each year. While they always don't work out, it's great to see a company moving forward with new ideas!


SBNO: Standing But Not Operating. A ride is erect yet not running for a period of time. The most infamous would probably be Orphan Rocker.

Strata Coaster: A roller coaster that is 400-499 feet. Under 5 of these exist worldwide.
