No one is quite sure at what point in history this massive alchemicaly powered train was built. It is known that it travels a full circuit around the massive city state in roughly 6 hours and that it is fully automated. it never seems to need maintenance and also seems to self clean every 6 hours as well. There are strict Guild regulations that state never to ride to the last station and those who have been overcome by curiosity and tried to do so have never been seen again. The line connects with all the major district’s in the city and is used daily by countless alchemists and civilians. All attempts to damage the train have been met with failure as have any attempts to stop the train. It runs its eternal journey set upon it by unknowable creators to wander like a benevolent ghost through the stations of this ancient city that seems young in comparison to its timeless existance.
