Lionel Legacy 4-12-2, #9000, Old Livery (6-11343)
The Union Pacific type locomotive is a unique locomotive to add to any collection. For those of us in love with big UP steam, it doesn't get any better than a 4-12-2 rigid frame locomotive! It was the largest non-articulated engine on the UP line.
I like the old livery. Not the era I am going to model but real trains didn't have 3 rails either!
Atlas O just announced more Steam Era Classics - Rebuilt Wood Refers in the PFE/Overland Shield Scheme. Might look pretty nice behind your 4-12-2 or Y-3...
Whenever I order Atlas O cars I usually order all four numbers. $80 bucks a pop is steep, but I know I'll have a heck of a time finding them later if I don't. Plus the shipping container makes it easier to store them.
