In the summer of 2012, Doug and I started an email exchange concerning a building for his railroad in Canada.
It started as just some ideas on my choice of architecture, roof and window, etc. He wanted something built after 1900 (the era is set in the 20s), but something not too run down, either.
But there were a few "rules". Doug wanted a 3 story building, and it had to be fairly sizable -
