iron ride
n.— «Some of the old iron rides in new dress, of course, have been revived. Perhaps they are even more devilish than they were in the old days. A twin-track roller coaster has been built and two sets of cars soar down the speedways racingg each other at 60 miles an hour.» —“Coney Island of the West” by Horace Sutton Washington Post, Times Herald July 16, 1972.
