Normally when you hear "red barn" you think of something where cows are milked and hay is stored. In the railfan world that would be the CP's cowled SD40-2's or SD40F's. I had a chance encounter with one about 10 years ago near Montreal and thought that was a big deal. Now that CMQ has acquired a few, they suddenly show up more often. Last week at Millinocket, ME and yesterday west of Lac Meganic, QC. I think I have another "bad penny" locomotive around. Anyway, here is the Flickr album I created of them and I assume it will see some additions down the road...
