Route 1: A route confirmed of the Norfolk Southern, here's a URL to their web page, so your guess which part of the network....but it will include the famous Horseshoe Curve! http://www.nscorp.com/nscportal/nscorp/ (based on pics released with the Leipzig press kit and Rick's comment).
Route 2: Unknown, but could include a BNSF route, for the BNSF Dash 9 diesel. (<Educated guess, corrected.)
Route 3: Unknown, but it would be nice if it was narrow gauge. (<Big hint.)
(Boxed routes - could be anything from three to six in total, in my opinion.)
