The Wonder Woman Golden Lasso Coaster opened on May 12, 2018, at Six Flags Fiesta Texas in San Antonio, becoming the world’s first single-rail roller coaster to open to the public. Built by Rocky Mountain Construction, it introduced the company’s Raptor track, a slender single steel rail only about 15.5 inches wide that riders straddle one per row instead of sitting side by side.
Rising 113 feet above a former rock quarry, the coaster was also the first named after a female superhero, tying its theming to DC Comics icon Wonder Woman. Since 2018 it has gotten company: a near-twin called RailBlazer opened the same year at California’s Great America, and a larger sibling, Wonder Woman Flight of Courage, debuted at Six Flags Magic Mountain in 2022. Here’s how the original stacks up, plus the height rules, ride experience, and trip-planning details you need before you go.
Quick Answer
Wonder Woman Golden Lasso Coaster is a 113-foot Rocky Mountain Construction single-rail coaster at Six Flags Fiesta Texas in San Antonio. It opened May 12, 2018 as the world’s first single-rail coaster, hits 52 mph after a 100-foot drop, and has a 48-inch height requirement. Riders sit inline, straddling a single steel rail, through three inversions.
Stats at a Glance
Park: Six Flags Fiesta Texas, San Antonio, Texas. Manufacturer: Rocky Mountain Construction. Opened: May 12, 2018. Height: 113 feet. Top speed: 52 mph. Length: 1,800 feet. Inversions: 3 (dive loop, cutback, corkscrew). Height requirement: 48 inches (122 cm). Track type: Single-rail (Raptor), about 15.5 inches wide. Location in park: the Rockville section.
The Ride Experience
Riders board single-file cars and straddle a single steel eye-beam rail rather than the twin rails of a conventional coaster, which gives the train a distinctive rocking sensation through turns. After a 100-foot drop, the layout twists through three inversions at a maximum vertical angle of 90 degrees.
Six Flags engineered a continuously moving station for the ride, so its trains rarely stop to load and unload. Guests are pre-grouped in the station so the single-file boarding process keeps flowing, letting the coaster handle roughly 600 riders per hour despite the one-across seating.
Height Requirement and Who Can Ride
You must be at least 48 inches (122 cm) tall to ride. Because seating is inline rather than side-by-side, there’s no bench-style seat for a smaller child to share with an adult, so the height rule is enforced strictly at the station.
The ride does not offer a dedicated single-rider line, but it does accept Fast Lane / Flash Pass line-skipping access and offers on-ride photos. Guests with mobility or sensory concerns can check the ride’s accessibility guide, available via a QR code posted at the entrance.
How a Single-Rail Raptor Coaster Works
The coaster served as one of two 2018 prototypes for Rocky Mountain Construction’s Raptor track system, developed by engineer Alan Schilke to allow tighter, more fluid layouts than twin-rail track permits. Instead of two parallel rails, trains ride atop one narrow steel rail, with riders’ legs hanging on either side, which lets RMC design sharper turns and more compact inversions in a smaller footprint.
Six Raptor-track coasters have opened worldwide: Wonder Woman Golden Lasso Coaster and its mirror-image twin RailBlazer (both 2018), Jersey Devil Coaster at Six Flags Great Adventure and Stunt Pilot at Silverwood Theme Park (both 2021), the larger-format Wonder Woman Flight of Courage at Six Flags Magic Mountain (2022), and Fire Runner at Lost Island Theme Park (2025). RMC also builds a bigger single-rail model called T-Rex, though none had opened publicly as of this writing.
Golden Lasso vs. RailBlazer vs. Flight of Courage
It’s easy to mix these up since all three share Wonder Woman branding or single-rail technology. Golden Lasso Coaster was first to open (May 2018) and set the single-rail category in motion. RailBlazer opened later that same year at California’s Great America, running essentially the same Raptor layout in reverse.
Wonder Woman Flight of Courage at Six Flags Magic Mountain is a different, larger coaster: it opened in 2022 at 131 feet tall and 58 mph, making it the world’s tallest and longest single-rail coaster, a record Golden Lasso Coaster no longer holds for height or speed. Golden Lasso Coaster remains the original, the first to carry the Wonder Woman name, and the shorter, more compact of the two Six Flags Wonder Woman rides.
2023-2024 Refurbishment and New Trains
The coaster closed on July 5, 2023, for a two-phase refurbishment addressing wear from being one of RMC’s original single-rail prototypes. Phase one covered station, track, and control-system upgrades, and the ride reopened on September 29, 2023.
Phase two, completed in 2024, replaced the original trains with three new Generation 2 single-rail trains built by Rocky Mountain Construction. The new trains use updated restraint systems designed to reduce lateral forces on riders, smoothing out the ride without removing its inversions or intensity. After test rehearsals in late June 2024, the coaster fully reopened to guests in early July 2024.
History and Origins
The ride replaced the Power Surge water ride and was originally slated to open in March 2018 before two delays pushed its debut to May 12, 2018. Its success in proving out the Raptor track helped establish single-rail coasters as a category RMC has since expanded to parks worldwide.
