Re: C16, C17, C18, C19 - Class 56

For an alternative source on the Class 56...check out the DSP&P's Baldwin 2-8-0s such as 191. As I recall, the biggest difference between the Class 56 and Class 60 locomotives was 4" of boiler diameter and the accompanying weight. I tend to recall that the Silverton RR had a slight preference for the Class 56 engines.

I would also point out that little of the original Class 60 locomotives still exist on the surviving C-16s. I would expect that the same holds for the Class 70/C-19. The C-18s on the other hand, were of a more modern design...and I don't recall reading about such extensive changes.

I'm sure that someone else can chime in with far more info on the subject...but I tend to recall that the C-17s were un-rebuilt locomotives...Perhaps Class 70.
