'East Coast News Photo' posted a video showing one of Ringling Brothers two circus trains as it rolled through Bethlehem on Tuesday, April 2, 2013. I had no idea that each are about a mile long.
The dual engines pull about 20 freight cars and around 40 passenger cars. I'm not sure whether this was the 'Blue' or 'Red' Tour. I'm also not sure where it was headed. I do know it wasn't the 'Gold' tour because that one uses trucks only.
Imagine how much it cost to keep just this one tour on the road
