I recently found the old
Otto Perry's Rio Grande Southern film in full on YouTube. The exciting part for C&S fans is that there is extensive color film footage of former C&S 74 towards the end pulling two excursions on the line. It is stunning to see her in action.
Here is a post with some background on 74 and the video.
Enjoy!
