This is my first ever O Scale loco. Started in HO Scale in 1978, switched to N Scale in 1999, switched back to HO scale in 2009. Hobby was paused from 2013 until I started building my roster again in May 2020. Now I am multi-scale between O Scale and HO. It is my wife's fault and all started with us deciding if we wanted the HO Scale, S Scale, or O Scale Polar Express for Christmas. We loved the O scale....which got my juices going...and next thing you know.......BOOM, my 1st O scale loco. My O scale shelf layout will really be mainline railfanning with the old Hill Lines (Great Northern, Northern Pacific, and Burlington). The detail on this thing blew me away.
