This is a mobile city that I created and yes, was inspired by mortal engines. The concept is that Arachnis has invaded earth and imagine the Matrix, but with alien spiders and Swarm Nodes everywhere. The last of the humans reside in Quadrant 3 and are trying to overtake her scourge and reclaim what they can.
People have also mentioned it reminds them of something from WarHammer 40k.
Here’s a quick video of the build.

Honestly, both. Some of the sections are held together with chains, while some others “snap” in with the bar/clip method. It is all about weight distribution.
