Espee Websites

In your opinion, what are some really good websites featuring Southern Pacific locos and rolling stock?

I've looked a quite a few, but I'm sure there are some good ones I've missed.

Thanks

I like going to http://sptco.proboards107.com for the type of information you're talking about.

Here are some of the best SP resources I've found:
Espee Modelers Homepage
Joel's Southern Pacific in the Cascades
Nor-Cal SP Connection
And of course, the Southern Pacific Historical & Technical Society
They all have links to other related pages.

If you're looking for vintage pictures, there are a lot at Robert Morris's SP Photo Index and a few more at Ron Goodenow's Attic: Southern Pacific. There are also photos at Rails Northwest: SP and I have some SP pictures on the Union Pacific Page of my own site.
