Every so often Peter Norman (swoofty) floods flickr with great train models. While this is great for LEGO train fans it makes life a bit difficult for me in choosing what to blog. This time I decided that the most novel of them all was a heavily weathered old Alco RS-1. Weathering in LEGO is hard enough at a small level but attempting it at this scale is even harder. I think Peter has made an admirable job of it here.
