Mr. Freeze (roller coaster)

On December 18, 1996, Six Flags Over Texas announced that Mr. Freeze would be added to the park.[4] Premier Rides was hired to build a new shuttle coaster using an LIM launch system.[2] It was billed as the tallest and fastest roller coaster in Texas. In addition, Mr. Freeze would be the second highest attraction at Six Flags Over Texas, with the tallest being the park's Oil Derrick observation tower.[4] Just a month later in January 1997, it was confirmed that Six Flags St. Louis would be receiving a mirror clone of the ride. The coaster would be placed in the center of the park. This would cause the park's Spain section to be renamed DC Comics Plaza.[5]

Mr. Freeze: Reverse Blast at Six Flags Over Texas

Mr. Freeze was planned to open in May 1997 to coincide with the release of Batman & Robin.[6] Arnold Schwarzenegger and George Clooney were scheduled to appear at the opening of Gotham City at Six Flags Over Texas and be the first to ride it, but problems with the launch system delayed its opening to 1998.[7] During Mr. Freeze's test runs, the LIM motors had issues with overheating and Six Flags officials could not provide the full thrust necessary to operate the ride consistently at high speeds.[8] Park management wasn't concerned, as Flight of Fear at Kings Dominion in Virginia also had issues with the launch system.[9] One of Mr. Freeze's trains suffered damage when the launch system closed onto the fins. The train was removed for adjustments and was later put back in place.[10]

The Over Texas location was originally located in the Goodtimes Square section of the park. When Batman: The Ride debuted in 1999, the surrounding area was renamed Gotham City.[11] On October 3, 2000, the ride closed due to an issue with one of the trains.[12]

When it first opened, Mr. Freeze used over-the-shoulder restraints (commonly called OTSRs), which were replaced with individual ratcheting lap bars for the 2002 season at both locations.[2][3]

In June 2006, all Premier Rides' LIM roller coasters were closed as they underwent emergency inspection after an accident on the now-defunct Batman & Robin: The Chiller where a wheel fell off on the lowest part of the track. This problem apparently existed on all of Premier Rides' coasters with booster LIMs. New wheels and bearings were ordered and replaced.

Both roller coasters were originally painted in light blue. The Texas Mr. Freeze received a new paint job that was completed in 2007. Now, the rest of the track is painted a bright red and the supports are dark blue. For 2009, the St. Louis Mr. Freeze was repainted with dark blue track and supports.

On March 22, 2012, Six Flags announced that both versions of Mr. Freeze roller coasters at Six Flags Over Texas and Six Flags St. Louis would feature backwards facing trains and be renamed Mr. Freeze: Reverse Blast.[13] The St. Louis version reopened on May 5, 2012,[14] with the help of David Freese (then a St. Louis Cardinals baseball player).[15] The attraction reopened at Six Flags Over Texas on May 12, 2012. Vanilla Ice performed a concert at the opening.[16][17]

At Six Flags Over Texas, guests walk into Snowy's Cones by passing under the mouth. Inside the factory, guests make a left turn and start on the lower level, where they approach some paths. In the center, there is a mixer and four flavor containers. These containers are vanilla, chocolate, strawberry and orange. Guests turn right and pass through a hallway with spray paint walls. An outdoor section of the queue can be found in this hallway. This area features switchbacks that run next to the Six Flags & Texas Railroad train tracks. Guests go up some ramps and navigate through the upper level. Along the way, there is a sign that says Home Of The Big Freeze. Now on the upper level, guests can get views of the lower level, the mixer and the flavor containers. Guests then head into the station, where they board the ride.

The Six Flags St. Louis location features a different queue line which takes place outside. Guests pass underneath the mouth to Snowy's Ice Cream Factory Tours, where they make a right-handed curve followed by a left-handed curve. These curves lead to a straight path and some small ramps. After making a left turn, guests walk down a long pathway where they can get views of the ride. Guests turn right and cross a bridge over the Thunder River rapids ride. Following the bridge, guests go down a curved ramp. Then, guests enter an area with switchbacks and a few passages. Several curved paths lead to a straight section of the pathway followed by a left turn. As guests get closer to the factory, there is a board with news and advertisements. After a right turn, guests enter the factory where they navigate through a hallway. Guests then climb the staircase and enter the loading station.

The ride begins when the train slides onto the main launch. Soon afterwards, an alarm is sounded and riders are boosted backwards through a 190-foot (58 m) tunnel and up into a 150-foot (46 m)-tall inside top hat that flips riders completely upside-down. This element is followed by a 113-foot (34 m) overbanked turn that banks riders at a 140-degree angle and a vertical spike. As the train climbs this spike and slows, it is gently pushed up almost all the way to the top by another set of LIMs. The train then freefalls down the tower back through the course.[2][3]
