Space Rail is reproduction of SpaceWarp, originally made by Bandai who stopped making Spacewarp around 1988, but continued to sell replacement parts until supplies were exhausted in 1995.
Spacewarp is line of build-it-yourself toy rolling ball "roller coasters" first made in the 1980's. Users cut lengths of track to the correct size from a single roll of thick plastic tubing, forming curves and loops held in place by plastic track rail holders which attach to metal rods held vertical in a black plastic base. Steel balls roll around the track and on to a battery-powered elevator that takes them to the top to start all over again
