Thunderbolt is a wooden roller coaster located at Six Flags New England. Opened in 1941, It was designed by Harry Baker and Harry Traver, and built by Joseph Drambour. Thunderbolt is the oldest roller coaster at Six Flags New England. It is also the oldest roller coaster in any Six Flags park (the Wild One at Six Flags America was built in 1917, but it was relocated from Paragon Park and has only been at Six Flags America since 1986). The single PTC train has 4 cars, and an individual lap bar and seatbelt for each person. An attendant has to manually unlock each car's lap bars by stepping on and pushing down a release bar at the front of each car.
