I think creative work in music and trains is a great combination. Joni Mitchell did it with music and fine art (painting). Rod Stewart obviously does it with music and model railroading, which can be thought of as a multi-faceted dynamic art project. Although not as famous as Rod, some of our Forum members also do creative work in music and trains.
Rod's layout looks amazing. He is probably sharing some of his enormous financial resources with numerous model train-related businesses, which I think is a good thing for many reasons.
