"Steel Roller Coaster"
This type of coaster is built with steel rails. Rather than the structure deciding whether the coaster is wood or steel, it is the side rails. On steel rails the coaster can be driven using electric induction motors. The most popular form, tubular steel, came about in the late 1950s, in which the rails consist entirely of hollow steel tubing, with elded steel rail spacers.
