Jargon Buster
In AIRtime ONline and on the Club website you will frequently see words, names, abbreviations, etc., that you may not be familiar with. This page contains a fairly comprehensive list of explanations to help you de-code and understand the coaster-speak and therefore get more enjoyment from the Club and the world of coasters!

#
4th Dimension: Individual cars of the train are designed to rotate on a horizontal axis. Instead of riding above the track, the seats are at the side of a 20ft wide vehicle which straddles the track, meaning that the seats can rotate 360 degrees as they travel the circuit (Example: X2, Magic Mountain).
A
Air Gate: The gate on a coaster station platform that stops rider from proceeding forward to the coaster train.
Air Launch/Powered: New style of coaster where the train is fired from the station using compressed air, resulting in extremely rapid but smooth acceleration (Example: Thrust Air 2000).
Airtime (Negative G's): The feeling of leaving your seat (weightlessness), usually experienced on the crests of hills, especially when riding the back of coasters. This is one of the favourite elements that coaster enthusiasts look for. Wooden coasters tend to give much greater airtime (also the name of the printed Club magazine!)
Anti-Rollback (Dog ratchet): A safety wedge that stops the train sliding backwards down the lift hill or other hill. When the ride is operating normally, the wedge makes the familiar clack-clack sound as the train ascends hills. Should the train stop for any reason, the wedge, which is on the base of the car grips onto grooved metal rails in the centre of the track, stopping the train from rolling backwards.
Arrow Dynamics: Defunct American manufacturer of steel coasters (Example: The Big One, BPB).

Storage Track: Track section away from the main circuit where the trains are stored when the coaster isn't operating.
S-Turn: Simple track manoeuvre which is used on suspended coasters to swing the cars first one way, then the other.
Suspended Coaster: The train rides below the track. The cars freely swing in relation to the track, and cannot contain inversions (Example: Vampire, Chessington World of Adventures).
Suspended Looping Coaster (SLC): Vekoma's name for their inverted coasters (Example: Infusion, BPB).
Swing Coaster: Another name for a suspended coaster.
Switchback Railway: The precursor to wooden coasters. A car would descend a slope, and after travelling up the other side, an operator would transfer it to a parallel track. It would then traverse this parallel track to its original starting point, where it would be transferred onto its first track - these transfers were known as switchbacks.
T
Terrain Coaster: Use of natural terrain features prominently in the ride (Best example: Boulderdash, Lake Compounce).
Themed: A coaster that has a special layout, effects, buildings, lighting, graphics or sound to create a particular theme to the ride.
Train: At least two cars connected together.
Transfer Track: Track section that moves to enable trains to be placed from the circuit onto the storage track, or vice-versa.
Transportable: A coaster that can be quickly dismantled and moved to different locations.
Trim Brake: A disliked brake at some point on the circuit used to slow the train to an acceptable speed, or to protect the riders from excessive G's. Sadly some coasters are over trim braked and made less exciting. Trim brakes cannot completely stop a train.
Turnaround: Where the track turns round at a point furthest from the station.
Twister: A coaster layout with numerous twists and turns in all directions (Example: Megafobia, Oakwood).

U
Up-Stop Wheels: Wheels on the underside of the train to prevent it from leaving the track on the crests of hills and during inversions.
V
Valleying: Term used when a coaster fails to complete its circuit, and gets stuck part-way around.
Vekoma: Dutch manufacturer who specialise in 'off the shelf' ride (Example: Boomerangs).
Vertical Drop: A ride containing a 90-degree vertical drop.
Vertical Lift: A rare feature where instead of a lift hill, a coaster car/train is lifted vertically upwards on a section of track that acts as a lift. When this section is aligned with the rest of the circuit at the top, the car/train moves forwards to complete the ride.
Vertical Loop: The rider turns totally upside down in a 360-degree circle (Example: Looping Stars).

W
Water Coaster: A ride that has conventional steel track, but small 10 or 12 passenger boats as the cars. The ride travels and drops through water similar to a log flume at several points during the ride.
Werner Stengel: Living legend coaster designer. He is responsible for over 430 coasters including 70% of the worlds top 50 coasters. These include Millennium Force at Cedar Point, Kingda Ka at Six Flag Great Adventure and Bizarro at Six Flags New England.
Wild Mouse: Coaster type featuring sharp drops, sudden turns and single cars.
Wood Coaster (Woodie): Defined by the fact that the track is made from laminated wood (irrelevant of structure material).
Wood Structure: The ride has a wood structure, but not necessarily a wood track.

X
X2: The first 4th dimension roller coaster, built at Six Flags Magic Mountain in California, USA
Y
Yeah!: The word often heard being yelled by enthusiasts as the coaster train descends down the first drop!
Z
Zero-G Roll: Similar to a heartline roll, but the track turns up and down during the inversion. This gives plenty of negative G's.
There are other terms and more manufacturers but this should be enough to help you understand the basics!
