Undecorated SD7 Project

Something that I'm intending to be chipping away at for a while is this Proto 2000 undecorated SD7 model that I dug out of the storage cupboard a couple of days ago.  The intention will be to letter it for the JSSX.

There's the shell, the chassis and motor, and a sealed baggie that's full with a lot of detail parts that came with the Proto kit.  Quite a set of instructions came with it too.

I bought these items from Otter Valley a couple of months ago with this engine in mind.  I thought I'd get two of the ESU basic style decoders because I figured it cant hurt to keep a spare around, right?

I plugged one of the decoders into the engine, and set it on the programming track beside the JSSX maintenance shed. 
Once programmed, I ran the SD7 around that layout looking just like this for about 20 minutes or so.  It ran really nicely in that trial run.

Here's a look at the inspiration for what I've got in mind for my model.
I'm hoping that the model turns out to look something like this.  I won't be including the orange P&W logo, that's for sure, and the bright white band below the dynamic brake blister won't have the Willamette & Pacific printed on it either.  And I'm also unsure about that light package.

I've got what's left of some old Microscale decals that I think I can use  for the SP "wings" on the front of the short hood.

I'll try to post progress as I go along, but I expect that this is going to take me a while.  Wish me luck.

Have a good week.  Do some modeling.
