Hi I’m looking into modeling these locos they are rebuilt B23-7’s classified as B23-S7 or B23-7R they look like Dash 8s only four were rebuilt #'s 3185-3188 I was wondering if anyone had plans,drawings,details on mods,or just a few mesurements. Don’t know who rebuilt them but they are painted CSX and Conrail here is one of the pics I have found http://www.rrpicturearchives.net/showPicture.aspx?id=151562
I can’t provide you with measurements. I can provide you with a link to more photos, though.
