For those of you who are fans of the 4070, there is a "new-old" video now available about her days on the Cuyahoga Valley Scenic Railroad.
"Steamin' in the Valley" was produced by Grant Geist's Berkshire Productions back in 1989, when the 4070 was running regularly on the CVSR. I digitally re-mastered this video from the D9 format master tape in HD. It's available on DVD and Blu-Ray from Yard Goat Images.
The video is very well produced, and runs 60 minutes.
