Well, Chris- A GP35 was 56' 2"; an SD45 was 65' 8" (EMD used the longer underframe of SD45 as a standard, which was then used for the SD38, SD39, and SD40). The main difference, however, is that the GPs were a B-B (4-4) wheel configuration, while (...) (25 years ago, 1-Dec-99, to lugnet.trains)

The GP35 is rather a boring engine in appearance. If you could pull off a GP30, that would be spectacular! Due to some "hacks" at design time, they have rather elaborate and ungainly fairing on the top of the hood which is a result of the (...) (25 years ago, 1-Dec-99, to lugnet.trains)

Thanks Larry, Looks like I'll have to head to the library. Before I try to build the power unit. Your "ersatz Alco" is that Big Red, the engine featured on your web page? Chris <snip everything Larry and I typed previously> (25 years ago, 2-Dec-99, to lugnet.trains)

(...) Yes. "Big red, an homage to the PA-1". I should build another one, when I get that one out it looks kind of primitive now. The state of the art in Lego Train Modeling has advanced a fair bit since december 1997 when that was built. (25 years ago, 2-Dec-99, to lugnet.trains)
