The British Rail flying saucer was a proposed space vehicle, designed and patented by British Rail during the 1970s^[1][2]. The flying saucer originally started as a proposal for a raiseable station platform. However, the project was revised and edited, and by the time the patent was filed had become a large passenger craft for interplanetary travel^[3].
