SD-9's and CDOT coaches

Back in May of 2007 I posted some pics of some SD

-9's in Goodman St. yard. Yesterday I saw two SD-9's in the yard that appeared to have been freshly painted for the Modoc Northern. I wonder if these units #'s 650 and 651 are the same 2 from last year? It's possible I guess, but I really don't know how long it takes to rebuild a locomotive from the ground up.

Also in the yard were a couple of Metro North cars just heading west. The CDOT coach the Governor Raymond E. Baldwin and the MN coach Mathew Vassar were being picked up off of 4 main when I pulled up. I grabbed a few shots even though the light was bad, eh, better than nothing I guess...
