I was wondering if it was still 30" gauge, too. Edaville cut and welded in a 'kink' in the mainrods to accommodate the 3" difference on each side. When we rebuilt her, Jason chose to scrap those and use a longer pin with new, straight rods.
I can't see from that picture if the rods have that modification, maybe someone else can chime in. Sure looks like it hasn't been "narrowed" yet, though.
It looks like that pipe would be the steam to the cylinders, but that would be an odd way to do it?
And who is that young girl in the cab??
While poking around for pictures of #5/10, I found this video which has some of the footage used in the
latest DVD from Restoration Stories on the SR&RL.
