The economics of maglev are still pretty questionable. The Japanese line is over a hundred billion Canadian dollars. In Japan where it connects a metro population of 30M with a metro population of 10M and a metro population of 20M it might work economically, but I am not sure it is a broadly usable technology unless costs come down considerably. Still more viable than hyperloop, of course. China or one of the gulf states may build one as a vanity project.
