Thanks for the reply. I did a little more digging and found this site: Train Art Index Page and more specifically: http://www.trainweb.org/willstrainart/Train_Art_files/Alco_line/C636.htm I thought I would post so that others may find something useful for them.
Please send a copy of all info regarding the Alco 636 to PAUL GRAF (wink wink, nudge nudge). Don Loffelman
