Ringling Brothers and Barnum and Bailey circus maintains two train-based shows, the Blue Tour and the Red Tour. Each train is a mile long with roughly 60 cars: 40 passenger cars and 20 freight. Rolling stock belonging to the circus use the reporting mark "RBBX". The Blue and Red Tours present a full three-ring production for two years each (taking off the month of December), visiting alternating major cities each year. Each train presents a different "edition" of the show, using a numbering scheme that dates back to circus origins in 1871 - the first year of P.T. Barnum's show. [source: Wikipedia]
I was lucky enough to get a heads up that the train would be traversing the NS Lehigh Line today so I headed over to get some video. This was taken in Steel City which is just east of Bethlehem PA.
