Hi pianoplayer88,
Incidentally for those who would like to know what it means, simply "Train of the Dwarfs" or "Dwarfs' Train".
Are you sure? What is the piece actually about? Zug can be a train, but it can also mean to wander or travel, the word being the noun form of the verb "ziehen" meaning literally to pull. "Ausziehen" or "Auszug" for example means to move out.
I just found a lovely fairy tale which is in German unfortunately - maybe the piece relates to it. The story is called "Zug der Zwerge". In it, dwarves live with people, and depend on their generosity. One greedy baker suspects the dwarves are "stealing" from him so he lays in wait at night. He knocks the cap off of some of the dwarves with his broom, and that makes them visible. The villagers are incensed that the dwarves have been stealing from them, and place a pot on a hill, in which each dwarf who has taken food must place a coin. They count thousands of coins. Villagers are angry at dwarves, dwarves are angry at villagers. The dwarves pack up their things and
move out. So "Zug" seems to have the meaning of wandering away. The dwarves are never seen again.
I would translate the title as "Exodus of the Dwarves".
If you wanted to stay with the train meaing, "Dwarf Train" would be more elegant. If it were a train belonging to dwarves, though, more likely it would be called Zwergzug or Zwergenzug.
