By 1975 Ashville, Ohio, had lost its depot, its newspaper and its industry, so the town built a museum out of what was left. The crown jewel is Teddy Boor’s patented motorised traffic light, a science-fiction orb that ran at Long and Main from 1932 to 1982 and holds the Guinness record for longest in operation.
