Re: Question...

Earl pretty much nailed it in his post, the D&RGW used all kinds of recyled stuff during the rebuild of the 3000 series boxcars. That said, not all of the 3000 series cars were completley dissasembled during the rebuilding. Car 3038, now a passenger car on the Georgetown Loop retains much of its original structure, including the wood carlines (roof ribs). "D&RG 3038" is stencilled in black over the doors (the original AC&F lettering) on the inside of the car, as well as "D&RGW 3038" in white (applied during the rebuild). These are still visable inside the car today. Also as the siding was pulled off of the car, it was evident that some of the wall structure was original and some was replaced in the 1920's rebuild.
From my limited experience working on 3000 series boxcars (3148, 3219, 3038 and the ex Sumpter car that burned last year whose number escapes me) it seems that there was nothing standard about the rebuilds. Some cars appear to have been completley disassembled and rebuilt with new parts, some received only a few needed structural repairs. I have seen cars that retain their original wood cars lines and at least three different types of metal carlines (ranging from newly made to cutdown standard gauge parts) to at least one car (3222 which sits on the ground in Alamosa)that has a mix of metal and composite wood/metal car lines.
Enough useless trivia for now!
