A closer look
Long before Six Flags, William Bridges Adams patented a rail system that threw actual passenger trains through a massive vertical loop just for the thrill of it. The Centrifugal Railway debuted in the 1840s, using gravity and pure kinetic terror to keep the open-top cars pinned to the tracks without seatbelts. It was marketed as a grand scientific exhibit, mostly because 'paying to risk a broken neck' didn't test well with polite Victorian society.
