Railfan Atlas is a beautiful map interface for exploring Flickr's railroad photography. The project started scouring Flickr for train photos in April, 2014, and has since become one of the largest databases of railroad photography on the internet. It's been covered by Railfan & Railroad Magazine; the Trains Magazine Blog, and CityLab.
