Train Location #6. The Hub Building At The North Pole
A massive railway station – the biggest in the world.
Domed roof, many many tracks directly below the dome.
Don’t know if this exists, may have to build it or use VFX to achieve it.
A rendition of the hub is foil stamped inside the cover of the book.
I even built a massing model to see how big it needs to be. It needs to be much bigger!
