For those who love Scotland, I just finished watching “Most Luxurious Train Journeys - Scotland” hosted by Alan Cumming.
Thoroughly enjoyed it. He does a good job of balancing the insider view of the train journey and his usual wee bit of humor with the history and culture of the lines, stations, and sites. Gorgeous scenery!
