Starting with a simple case, the distance from Durango to Silverton as the crown flies (per Wolfram Alpha) is 38.57 miles or 203,650 feet. This is 1,272 feet in N scale, 2,340 feet in HO scale or 4,242 feet in O scale.

For comparison, Hanger one at Moffat Field (one of the world's largest freestanding structures per wikipedia), is 1,133 feet long, the Queen Mary is 1,019 feet long, the Hindenburg was 803.8 feet and a 747-400 is 231 feet. So, a very large building!
