Well, I don't have focused in an concrete area of Rio Grande (in fact, I'm still doing the layout blueprints
). It will start as an small switching layout that I can grow later. My -intended- time window are between mid 50's to mid 70's (well, I
try to stay around 1965/1970
), so I can have lots of different locomotives: F's, GP30's, GP35's, GP40's, PA's, SD's...
If I should to choose a particular zone, the Grand Junction-Provo-Ogden operation is one of my favourites, with D&RGW, UP and WP trains. The Joint Line is also a big winner, because you can have trains of MP, AT&SF, D&RGW, CB&Q... Not an easy decission!
