I was sad to see the closure of La Vibora at Six Flags Over Texas on November 4, 2024. As far as I can tell it was the last standing of what was known as the Swiss Bob roller coaster by Intamin. On a Swiss Bob a bobsled like vehicle is taken up a lift hill and then released into a tubular track to free roll and mimic the action of Olympic bobsledding. Most classify this style of ride as a roller coaster even though it lacks traditional track. La Vibora is being removed to make room for a new dive coaster for 2026 (here’s a video of the demolition from Amusement Source), which no doubt will be a great addition for the park, but the uniqueness of the Swiss Bob will surely be missed.
