Mobile Cities & Mega-Vehicles

Mortal Engines is a book series and a movie about a future wherein mobile cities on tracks scoured the countryside for essential materials and occasionally consumed other moveable municipalities. Mortal Engines was written by Philip Reeve and published in 2001. The film adaptation premiered on 27 November 2018. It wasn't a new idea. Christopher Priest had written a book called The Inverted World in the 1970s and James Blish wrote about Cities in Flight in the 1960s. What follows is some illustrations about traveling cities from a wide variety of artists. I've posted about tracked cities previously so I'll instead post art about giant floating cities and railroad traveling cities in this thread.
