Shock Wave is a Schwarzkopf sit-down roller coaster located at Six Flags Over Texas in Arlington, Texas. Contrary to popular belief, it was not the first roller coaster to feature back to back vertical loops. That distinction goes to Double Loop at Geauga Lake, which opened in 1977, a year before Shock Wave. Shock Wave is located at the very edge of the park, easily seen from the Interstate Highway 30.
While not the fastest, scariest, or most technically advanced ride today, it still is ideal for younger riders looking to go on their first "upside down" roller coaster as well as nostalgics and coaster enthusiasts
The ride is built on Johnson Creek real estate, and had to temporarily close in the 2004 season because of a flood. Shock Wave temporarily closed again in early 2008 for an extensive remodeling.
After the 116 feet (35 meter) lift hill, a U-Turn with a slight dip follows. The coaster then goes down the first drop into the back-to-back loops, with peak forces at 5.9G. The train then travels up a hill into the mid-course brake run. The ride then turns right and dives down and back up. The ride then turns left and drops down again. The final element is a hill with a left turn that goes into a 270 deg helix to the right, before returning to the station.
Since it's opening, Shock Wave has had many colour schemes. On opening, the track and supports were all-white. since then, the coaster has been painted dark-blue, light-blue, silver, white track with yellow supports and dark-blue with red supports.
Currently, the ride is painted green with blue supports.
