I was watching some You tube movies people have captured and shared with us. Right now I try and find Union Pacific shares and came across a few on Donner pass in Calif. which made me feel more comfortable having a tight turn on a main line which is something we O scalers have to contend with when building a layout. I went to a aerial photo map of the area to see where one finds anything that could be used as a fact vs a fantasy in ones layout. I found two areas on the pass where mainline trains and one has a nice curve. https://www.google.com/maps/pl...ue+Canyon,+CAemail@example.com,-120.7115099,1426m/data=!3m1!1e3!4m5!3m4!1s0x809b9758913d9b1b:0x1b62c2e7707a8047!8m2!3d39.2571225!4d-120.711046
I was really looking for a shot in share that I saw that looked like the photographer used a bubble eye lens. vs a real movie of a tight turn. The train just looked like it curved so tight. Unreal but nice.
