Six Flags

Six Flags is the world's largest amusement park corporation, operating 27 properties, including theme parks and water parks, across North America. For their 2007 season, Six Flags collaborated with HiT Entertainment to introduce Thomas and Friends-themed areas across some of their parks. Thomas Town would be featured at various locations, including: In 2010, Six Flags announced that they would begin to remove several licensed characters, including Thomas & Friends, from their parks as a cost-cutting measure following a 2009 bankruptcy. Thomas Town would be subsequently overhauled into Whistlestop Park from 2011 to 2013 except for the one at Six Flags Discovery Kingdom, which would instead be converted to the nautical-themed Seaside Junction.
