LIM LAUNCHED COASTERS

Although a somewhat-dated launch technology, LIM (Linear Induction Motors) technology is a form of electro-magnetic propulsion that was the first launch method to see widespread use by numerous companies. LIMs use two opposing magnetic fields that repel each other, thus creating motion as metal fins/blades are propelled through the magnetic field. They are generally used to replace a traditional lift hill and do not contain any moving parts.

The Original

PREMIER LIM BOWL

Poltergeist Six Flags Fiesta Texas
Poltergeist at Six Flags Fiesta Texas in the USA.

Also known as spaghetti bowl coasters, these tightly-packed Premier looping coasters begin with an LIM launch from the station. The rides feature four inversions packed into a twisted layout of turns, helixes, and hills. Most LIM Bowl trains have been retrofitted with lap bars in place of their OTSRs (over the shoulder restraints)!

The first two models were enclosed and called Flight of Fear. They opened in 1996 at Kings Dominion in Virginia and Kings Island in Ohio (both in the USA). Three years later two more opened at Six Flags America (Joker’s Jinx) near Washington DC and Six Flags Fiesta Texas (Poltergeist) in the USA.

Operating examples:

Joker’s Jinx at Six Flags America, USA
Poltergeist at Six Flags Fiesta Texas, USA
Flight of Fear at Kings Island, USA

 

Variations

PREMIER LIM SHUTTLE LOOP COASTER

Mr. Freeze Reverse Blast Six Flags St. Louis
Mr. Freeze Reverse Blast at Six Flags St. Louis in Missouri, USA.

Premier LIM Shuttle Loop Coasters are famous for their incredibly intense and out-of-control ride experiences. The main production version was manufactured in 1998 and consists of a launch, inverted top hat, overbanked turn, and vertical reverse spike where the train goes up the spike and falls back down to retrace the circuit backwards.

Operating examples:

Mr. Freeze at Six Flags St. Louis, USA
Mr. Freeze at Six Flags Over Texas, USA

In 2012 Six Flags reversed the seating so riders face backwards and the coasters were renamed to Mr. Freeze Reverse Blast.

In 1998 Premier also built Batman and Robin: The Chiller, a pair of dueling LIM coasters featuring slightly different elements along a similar track pattern. Although a park guest favorite, the coaster suffered from technical issues for years and was sold in 2008 to Beto Carrero World in Brazil, were it has sat in storage ever since.

Speed The Ride NASCAR Café Cafe
Speed – The Ride at NASCAR Café on the Las Vegas strip in Nevada, USA.

Two years after the first LIM Shuttle Loop Coasters opened, Premier built another called Speed – The Ride at the NASCAR Café in Nevada,USA. It was very similar to the originals, but had a different layout without the inverted top hat. The Sahara Hotel and Casino that housed the NASCAR Café was demolished in 2011 and the disassembled coaster still sits in a nearby parking lot.

PREMIER LIM TRIPLE LAUNCH COASTER

Premier’s most well known LIM launch coasters are the Revenge of the Mummy coasters at the Universal Studios parks in Florida, California and Singapore. The first opened in Orlando and Hollywood in 2004, with the one in the Far East coming some six years later. Like the original Flight of Fear LIM Bowl coasters, these three are also enclosed. However, the coasters do not invert and feature three launches throughout the circuit, but do not have identical layouts.

Operating example:

Revenge of the Mummy at Universal Studios Hollywood, USA

Back Lot Stunt Coaster Kings Dominion

In 2005 Premier manufactured another set of triple LIM launch coasters called Italian Job: Stunt Track at Canada’s Wonderland and Kings Island in Ohio, USA. A third was added the following year at Kings Dominion in Virginia, USA, and all three had the name changed to Back Lot Stunt Coaster after Cedar Fair purchased the parks from Paramount in 2008.

Operating examples:

INTAMIN SUSPENDED CATAPULT COASTER

Volcano: The Blast Coaster Kings Dominion
Volcano: The Blast Coaster at Kings Dominion in Virginia, USA.

In 1998, a year after the company’s LSM Launched Freefall coasters debuted, Intamin introduced the inverted LIM launched coaster with Volcano: The Blast Coaster at Kings Dominion in Virginia, USA. Using a second LIM launch to boost the train out of the top of the man-made volcano, this model paved the way for future Impulse designs to be what they are today.

Operating example:

INTAMIN IMPULSE COASTER

Possessed Dorney Park
Possessed at Dorney Park in Pennsylvania, USA.

In 1998 Intamin manufactured their first LIM launched shuttle coaster – Linear Gale at Tokyo Dome City in Japan. Two years later they created the first twisted version – Steel Venom at Geauga Lake in Ohio (now Possessed at Dorney Park in Pennsylvania), USA. These inverted coasters launch the seven car train four times, forwards then backwards, out of the station and up vertical spikes. The forward spike is twisted, whereas the rear spike is straight with a holding brake that suspends riders for a few seconds during the final decent.

There are a few variations to the standard, with Wicked Twister at Cedar Point in Ohio having twisted vertical spikes at both ends and V2: Vertical Velocity at Six Flags Discovery Kingdom in California having a 45° inclined front spike due to restricted airspace over the park.

Operating examples:

Vertical Velocity at Six Flags Great America, USA
Possessed at Dorney Park, USA
V2: Vertical Velocity at Six Flags Discovery Kingdom, USA
Steel Venom at Valleyfair!, USA
