This time we will visit the most boring location of the Northern Meridian. In fact, this is a redrawing of this location, which I painted a few years ago. Frozen Route is just a railroad that runs across the surface and goes far to the south. It is also called the Greed Route, during this route you can find many T-crystals frozen into the ice, some greedy exalted with the help of vehicles tried to pull these orange crystals out of the ice, but sometimes thin ice cracked and they sank in ice water. So be careful.
This location is not remarkable, except for ice caves and snow fields there is nothing here.
Also since the location in itself has no special features of its own, I can see some incident happening within the trains to surprise people when they least expect it, like stuff blowing up!
From any train at the terminal station, you can disconnect the railway carriage and turn the train in opposite direction. This is not a secret scifi technology, there would be a traffic collapse if humanity could not turn back its trains.
