For those of you into standard gauge steam check this out
http://research.nprha.org

With the diagrams on that site and a good set of photos you would have more than enough info to be building more locos than you could get through in two lifetimes!

Regards

Bunny,
Thanks for the link. To get straight to the diagrams go to this LINK. Bummer for me, all the engines I'm interested in are only 600 x images. Hard to read the numbers on those /DesktopModules/NTForums/themes/mls/emoticons/sad.gif

On this loco, it looks to me like the trailing wheels are two different sizes. Is that right or am I missing something?:

Ray, that IS correct. That is a common feature of early-style [ie, pre-WW2] Northerns built by ALCO in Schenectady NY and Baldwin in Philly...all of my H0 versions, GN and SP&S, are like that too.

Some very useful information there. Thanks for heads up David.

The NPRHA site also contains a collection of freight car diagrams (including many of the standard designs) that would also be useful for the poor misguided souls out there who don't model the NP. From the Company Store section of the site, you can also order a CD with a collection of high-resolution NP steam locomotive drawings (actual scale drawings rather than the simple diagrams found on the website). Lots of good stuff there.
