Is anyone familiar with a train photo website designed to 'follow' trains across the country by having users post photos of engines and rolling stock in taking in various locations? As I recall, one could search specific engines and/or rolling stock by number in hopes of finding photos of that piece of equiptment in different locations. I seem to remember various stats were available as well, along the lines of 'most photographed', or 'greatest distance between photographed locations', or something of the like. There may have even been historical info for engines available as well.

I've checked the usual suspects, such as railpictures.net, railroadpix.com and railphotos.com. None of these sites appears to be the site I stumbled across last year.

Thanks in advance,
