Jörmungandr (Your-moon-Gahn-dehr)

Jörmungandr - named after a serpentine titan that existed before The Shattering, is a large, magical train operated by Intern. Rail.  It is able to create track for itself as it travels, even managing to deform the terrain, build bridges and tunnels, and similar fantastical feats of engineering.  It travels slowly, requiring a well-trained staff and a constant supply of new resources.  Rumors abound about what sort of magic powers this behemoth, but Craig, the CEO of Intern. Rail, refuses to divulge this information even to his own staff.
