Hi all- My great-grandfather had a pretty extensive layout in his attic when I was young. I'm almost certain it was all HO gauge. It's now been 20 years since he passed and I've seen those trains, but now that I've got some space I'd like to start my own layout. I recall him having two locos, one dark blue and one black, that closely resemble the American Flyer Royal Blue #350 loco. Has anyone ever come across an HO loco that is nearly identical to the #350? Maybe he did have some S gauge mixed in with the HO, but it's been so long I'm not sure. Any info is greatly appreciated! Thanks!
