Thanks to Karl S. of Trainboard. He put up video of Colorado & Southern No. 9 that he shot vertically using a small handheld back during the short fall season. Yes, that's real snow coming down. To quote Karl, "...On the next run, it was snowing so hard you couldn't barely see from one end of the train to the other. Riding behind No. 9 in an open car in the blinding snow was AWESOME!!!"
Thanks, Karl, for some decent video of Colorado's newest old locomotive!
