Last Saturday one of our National Capital Tracker members started the day at his LHS, picking up his Vision Line Big Boy. He brought it right to the B&O Museum to test it out. Here's video of its first back and forth testing. I have been trying to get rid of the last 9 seconds of chaos on the video, but have been unsuccessful so far with Quick time 7 pro and the You tube editor. Finally, I said the heck with it and posted as is.
