This was the only local subway (and the only privately owned subway in the world) when I was a kid. Originally known as the Leonard's M&O Subway, later the Tandy Center Subway when the building changed hands. It ran 0.7 miles and had 5 stops. 4 to the parking lot and 1 at the shopping mall/corporate headquarters building it served and only lasted from 1963 to 2002. It feels like a weird fever dream now.
