Thanks for doing all 3 of these, especially during the fall. I was born in and lived in PA though 1965. I still remember the beautiful scenery, but never saw much of the scenery in this part.

I hope there are more videos like this one. It is AWESOME to watch.

Thank you for the video(s) and posting this. Nice way for this Canadian to see this lovely part of the continent.

2:55 By by catenary. It's often been wished that the Pennsylvania RR between Harrisburg and Pittsburg would have been electrified for fast passenger service, but with low height catenary of the build period future double stack freight would have not been possible. It's strange Amtrak would use a Diesel locomotive between Philadelphia and Harrisburg when electric is viable. Washington DC is talking about making zero emission locomotives a requirement and NYC has for a very long time. My guess is that using the Diesel allows keeping the train consist the same without the need to do an engine swap at Harrisburg. The RR corridor between Philadelphia and Harrisburg has sections with no barrier fencing between the rail corridor and adjacent properties. That typically would indicate the rail corridor is only rated up to a maximum of 110 mph. There are no at--grade road crossings which are the most difficult to eliminate. I thought the railroad alignment was beautifully elegant holding a high speed consistent alignment through the very hilly terrain. It would be nice to include train speed. I've seen road racing video data capture systems used by amateurs (they don't make money at it) that include not just speed, but lots of other data on the video screen.

What did you use to record the radio chatter?

The freight trains you pass... how do you know the train #'s and endpoints? Via scanner?
