Here's another "goof" engine: Guilford has/had some SP39. As there is no SD39 available in H0 scale, I decided to repaint a Kato SD38-2. Except for the trucks (which I my change in the near future), it looks not very different to the real SD39 in my eyes...

The SD38 to 40-2 series will always be my most favorite Road Units ^^ Great work there~

Thanks for your comment! What about the SD45? It's still my most favorite EMD 6 axle engine.

Within the next weeks, I'll convert a Kato PRR SD45 into Guilfords #681 with high short hood. That engine is quite impressive because of it's massive body with the high nose...

I think it's more about the wider decks between the front and the rear of the ends to the cab body that does it for me. It's like a battleship on the rails
