Very late, but I finally got an idea for Trains
Crossing the red linesOne of the greatest inventions of our history, which according to most historians marks the turning point from the age of recovery dominated by wovenman suppression of knowledge into the Renaissance age, is that of Orichalcum and the "Āltepētl*" levitating train.
Alchemy has a long history of experimentation, especially in the context of Cetricity and whaleblood alchemy. Orichalcum is the product of such experimentation from Mimatqui, the great alchemist and inventor: An alloy composed mostly of copper, tin and small quantities of powdered whale bone and blood, exposed to Cetricity during melting and solidification. The result is a deep red metal with peculiar properties: it is very malleable, shiny, low friction and resistant to wear, is an exceptional conductor better than even tattooed skin… and when it is charged, magnetic rocks levitate on it.
This last property turned out to be crucial for a revolution in transit technology: The levitating train. A rail is laid between the destinations one wishes to connect consisting of:
-a structural core, most often made of stone
-A layer of Orichalcun wrapped around it
And then a Cetric current is applied energizing the rail.
At this point the vehicle, consisting of a carriage (generally wooden) with a core of magnetic rocks in the middle of the floor which forms a housing for the rail, in which it is inserted and levitates. The result is amazing, removing nearly all resistance to motion. Sure, you still need to apply motive power and at the times engines were lacking resulting in solutions ranging from gently sloping gradients to horses and oxen, to sails. But undoubtedly this invention increased the carrying capacity of our civilization enormously, making land travel as convenient as sea travel and connecting cities all across the northern half of the continent.
PS: increased connections cause social upheaval, Wovenmen rule collapses, Twelve Bays confederacy happens
*"Āltepētl" (water-mountain) might be used metaphorically to describe something that is suspended or floating, not directly for levitation but conveying a sense of something above the ground.
Quarque provided a nice picture of what the train may look like, albeit probably at some time in the future as it is seems metal heavy
