I took this video on May 25th, 2013, and several months ago I released a much shorter version of this video on YouTube. It's a bit unusual in that the sound is a mixture of this steam locomotive, plus a Zlin acrobatic plane (possibly a Z526) that kept buzzing it. There's also a barking dog on the video. Unlike the earlier YouTube version of this video, the plane is actually on this one. The back story of the video is that I happened to be in Cercany at random. This was just a lucky catch, for both the locomotive and the plane.
