I put Echo Curve in along with the Park City Branch because that's what UP did at Echo
Photo (1) - Echo Curve and Park City Branch in both 1:1 scale and 1:160th scale:Come to think of it, that's why I put most of the curves in my layout, as well as scenery, structures, facilities, signals, rivers, rolling stock, engines, vehicles etc.
Cheerio!
