Eurostar is a portable inverted roller coaster that travels around to fairs in Germany. It is the first and largest portable inverted roller coaster. "Eurostar" was the brain child of Oscar Bruch. Bruch had created many portable coasters that contained loops including, ‘’Looping Star’’ and Thriller. The Inverted coaster was becoming increasingly popular in the mid ‘90s. Oscar Bruch saw potential in creating one that could be transported from fair to fair.

Ride experience

After leaving the station, the 28 passenger train makes a wide “U” turn to the lift at the back of the ride. Rides ascend the 98.91 foot chain lift hill. Once at the top of the lift, riders drop towards the right reaching speeds of 50.20 MPH at the bottom of the drop. Upon exiting the drop, the train navigates a large vertical loop that runs parallel to the lift. After the lift, riders experience a 121° overbanked left turn that leads into a zero-g roll. After the zero-g roll, riders make another left turn up into the first block brake. After exiting the block brake, riders make another left hand turn and navigate through two back-to-back corkscrews then make a right turn up into the second block brake. After the second block brake, riders experience a tight right hand downward helix and a small hill before hitting the final brake run and returning to the station.

Ride History

The creation of "Eurostar" was supervised under the Bruch Engineering Office. Unlike normal coasters, the task of creating Euro-Star was handed to many different subcontracted companies that specialized in roller coasters. Bruch Engineering Office coordinated each company’s interaction with each other. Bruch created a rough layout of what he wanted in the ride and went to Ingenieur Büro Stengel GmbH to design and engineer the ride from his idea. A detailed model was created and fabrication of ‘’Eurostar’’ could begin.

"Eurostar’s" control system was subcontracted to Intamin AG who designed and produced the system. Giovanola was subcontracted to produce the track, lift, and most of the electrical system. Mannhardt, a company located in Southern Germany, produced the supports, as well as the sole and chocks for the coaster. The company declared bankruptcy during construction. Bruch founded a “hive-off vehicle” to complete the construction phase and assure "Eurostar’s" completion.

Giovanola assembled the trains with components produced by an unknown Dutch company. MACK Rides created the “cash box” area. Johann Gerstlauer, whose brother Hurbert Gerstlauer who owns Gerstlauer Elektro GmbH, produced the station and exit area. Pelz, another company located in Southern Germany, Produced the ride’s lighting.

On July 20^th, 1995, "Eurostar" debuted at a fair in Düsseldorf after a six day delay. [ [http://www.coastersandmore.de/rides/eurostar/eurostar_eng.shtml Coastersandmore.com - Roller Coaster Magazine: Eurostar - Inverted Coaster by Oscar Bruch ] ]

Moving from fair to fair

The transporting of "Eurostar" has been accomplished by Siegfried Scholten and his team more than 60 times since the coaster debuted in 1995. Disassembling, transporting and reassembling "Eurostar" requires a minimum of eight days (a rare exception). It requires four cranes and 20 workers working around the clock in order to meet the assembly deadline on time at the next fair.

Disassembly

Disassembly of "Eurostar" usually takes about 10 days. When each piece is removed it is placed on a specific trailer created for that piece or pieces.

Transport

18 semi-trailer trucks are required for transporting "Eurostar". The trailers that house the ride during transport are customized with special mountings for each part.

Assembly

Assembly of "Eurostar" takes about 14 days to complete. Since "Eurostar" does not have a second sole, the whole ride must arrive on site at the next fair before assembly can begin.

The sole is the most complex part of assembling the coaster. All support points must be on the same level and the ride must be properly aligned to ensure the coaster stands straight so that the static and dynamic forces are led to the ground safely. To ensure this, sophisticated laser leveling instruments are used. Depending on the level of the ground, different sized wooden beams and planks are used to level out sections of the sole, just like for other portable rides.

Further assembly of "Eurostar" is purely routine. As the same with permanent coasters, each support is installed and the next track segment connected to it and fixed into position with large bolts.

The trains are transported on station track segments that hold elements of the station. These pieces are installed with the trains on track. The lift is installed similarly to the trains and station pieces. Segments of chain are left in each piece of the lift and are joined later after assembly.

Refurbishments

In time, the frequent assembly and disassembly of "Eurostar" cause the ride to become rough and unpleasant. The small footprint of the ride and tight layout amplified these discomforts. In 1995, the ride’s first year, a brief refurbishment consisted of stiffening track pieces with doweled joints between the spine of the track and the rails.

In 2003, "Eurostar" was assembled for another refurbishment at Gerstlauer Elektro GmbH after Oktoberfest 2003 where the ride received an upgrade to its electrical system. Measurements where also taken to relate forces to track positions in order to rework rough areas to be smoother. The optimal track layout was created after intensive calculations and new track tubes where bent and installed using the existing spines.

In 2004, before being assembled for the Düsseldorf fair, "Eurostar’s" zero-g roll, the left turn up into the first block brake after the zero-g roll and the left hand turn after the first block brake, where replaced. The doweled joints in the vertical loop had holes drilled into them to reduce noise and oscillation. Modification of the track connections was also done. The lift had a cover installed that would slide over the saw-tooth profile of the anti-rollbacks, making the surface smooth and eliminating noise created as the anti-rollbacks jumped between teeth. The change in the safety system required a control system to ensure rides safety. The trains speed is controlled and any variance in the speed causes the cover to be pulled aside to expose the saw-tooth so the anti-rollbacks can engage. Should the system fail, springs would push the cover aside to ensure the anti-rollbacks would engage incase an emergency would arise.

"Eurostar" received another upgrade in 2005 to the ride technology. The refurbishment cost one million Euros. [ [http://www.coastersandmore.de/rides/eurostar/eurostar_eng.shtml Coastersandmore.com - Roller Coaster Magazine: Eurostar - Inverted Coaster by Oscar Bruch ] ]
