I was pleased to see another instalment of Michael Portillo's North American rail tour on BBC this evening.
This focused on St.Paul and Minneapolis, and gave me some encouragement to visit the twin cities.
I was surprised to hear that rail magnate Mr. Hill was the man known as the "Empire Builder", rather than the train itself.
Commodore hotel in St. Paul looked rather cool, as did the glass skyways to protect against heat and cold in Minneapolis.
Not sure when I can get back to ride the rails stateside, but will certainly look to visit the twin cities when I do.
