All along the mountain, three parallel ground rails spiralled up it’s diameter along with the normal roads, and passed through stations in the outlying large towns near the city, themselves mounted into the mountain wall just like the city itself: it’s unique conception of suburban sprawl, no doubt, given the similar design language. Finally, the ground rails were carried by stone-buttressed and reinforced yet skeletal wooden bridges, and the roads were carried by beautiful smooth stone arched bridges, as both finally terminated into the presumed city of Canterlot.
