Not having to do with the trucks but the model in general, I would love to see some type of attaching method between the shell and LNR chassis. There isn't one to speak of currently. It would make life much easier.

^^^There will be. You know the slots in the brass at the back and front of the mechanism. A shaped part will slide in that will both hold the top in the right position and provide a light lock for the installation of an LED or light bulb.

Not off top of my head but I'll take a look. Glad you've thought of it already :thumbup:

Are the axles in the above design spaced exactly like they are on the LNR trucks? As opposed to the real distance on the real prototype?

Not trying to be nit picky - just trying to call your attention to things I've run into while working on my model.

Unfortunately I'm at work and the LnR is at home. You don't happen to have the wheel center to center measurement handy, do you?

That ^^^^ already looks better than the Lionel. On my design, the space between the truck side frame corner and the pilot stairs is very tight - literally tenths of a mm. Keep that in mind - you may have to do some modifications to the frames and/or stairs for the truck to be able to turn properly.

If you are still looking for more prototype details. The site listed below contains a ton of pictures and other info on a Southern Pacific GP9 that was refurbished to running condition. It is a non-dynamic brakes model with the air tanks on top.

I have a number of pictures of it myself so if you need something specific, I might have it. It is located in Niles Canyon near Sunol, CA, USA.
