@c.sam posted:jtrain, Years ago I wanted a set of the 'Aspen Leaf' PAs that I'd seen in photos and in N scale. It appeared to be a simple paint job so I decided to try it and ordered some D&RG decals. The 'high-water' look on most Wms diesels always bothered me and killed the 'massive, hunkered down' look of a real PA. Was able to add some balsa sides to the stock fuel tank of these Santa Fe's and paint for a much improved appearance. Part of the problem I think is that the Wms trucks are undersized as well exacerbating the visual problem. I was able to have an ABA set of these long before any manufacturer produced them in O Scale.
I thought it was just the fuel tank that was too small on the Williams. I have the MTH PA's and the trucks seem similar in size to the Williams, but the fuel tank is MUCH smaller on the Williams. I think that is the real problem. It seems like it would be an easy 3D printing job to print a correct scale-sized fuel tank for the Williams PA. I imagine that they would look pretty darn good with that "upgrade." Do you have a close up photo of your "upgraded" Williams PA's?
