I've been seeing a few interesting engines around the Norfolk Southern Training Center in McDonough, GA this year. I often don't have my camera with me when I get off of work in the morning, so I havn't been able to photograph them since their presence on the siding is not frequent enough to warrant dragging the camera with me every day. But when I see one, I try to remember the camera the next day. Here are a few of the engines that are getting rare on main lines.... The first is a SOU SD40-2 high hood.
