Cover art for Terror Train lyrics by Demons and Wizards

also about stephen king's "dark tower series." it's about a monorail train, named blaine, who is losing his/its sanity and only loves riddles. he makes a dead with the gunslinger and his ka-tet that if they can give him a riddle he can't solve, he'll take them through the wastelands safely. if not, he's going to derail at the end and kill them all.
