Blaine the Mono is the monorail train that transports Roland and his outlaws to the wastelands. Blaine is a machine with artificial intelligence, and his intelligence allows him to control the city's computers. Blaine is, in fact, the one who opens the door and allows Roland access to the locked room. Blaine, however, suffers with a mechanical malfunction that causes him to be angry, sullen and mean.
