Littmeister Weinberger Freiherr von Mikesch

Conductor. President of the International Sleeping Car Company, an elderly gentleman with a calm demeanor.
He was a knight heard in the last war. He and his beloved grandchildren are on board the Magic Arrow, the maiden train of the "Trans-European Express" project, which has just been completed.
He loves his only family member, his granddaughter Milch, and is taking good care of her. Although he raised a son before, this is her first time raising a girl, so it's a little awkward...
Weinberger had a son who was to become his successor, but he and his wife were killed in an accident two years ago, leaving the young Milch behind. The son and his wife were on a trip to inspect the railroads in the beaten path, and on their way home, the airliner they were boarding crashed on level ground just as it was about to land at the airfield in their hometown where the father and his beloved daughter were picking them up. All the passengers and crew on board were killed.
The "Trans-European Express" project was, so to speak, a gift to Weinberger's son and daughter-in-law. Rittmeister means "knight captain" and Freiherr means "baron". Von means "distinguished family.
Weinberger carries a Dillinger as a self-defense pistol, perhaps out of pride as a knight or to protect his granddaughter.
