Guy Wicksall
These videos are from Guy Wicksall's collection which was originally available on DVD.

This guy's videos and photos are top notch. They were taken between the 60s and 80s with high resolution film for their day. All the videos are well preserved with good color to them. He traveled all over the world and made videos of railroads in the UK, South Africa, South America, and of course the US. Given the timeframe of his US videos, he caught some truly classic videos of rail traffic at the time. It's important to note that there is little if any sound during the videos except for his occasional voice over explaining what he caught on tape.
Here's a couple of videos of the D&H and Erie.
