USA: Challenger hauls 6,000 ton circus train - video

[John Ashworth]

There's a video here of 4-6-6-4 'Challenger' no 3985 hauling the Ringling Brothers and Barnum & Bailey's circus train in September 2010. The consist was 65 cars, weighed over 6,000 tons and was more than a mile long. Unfortunately the noise of the helicopters drowns the beat of the loco in the early part of the video, but there's a good bit at the end.
