WM 734 performs a runby during a Carl Franz fall photo charter.
Myself and a few other railfans where yelled at because we used a flash to illuminate the leaves. The reason was that the flash shows up in the ones taking video and that they said it doesnt brighten the train. Ahh...the flash was to illuminate the leaves. Either way, I also took a video and watched it several times and didnt notice a flash in the video.
