2021 "Welcome Back" Trip to NS Pittsburgh Line - Selected Train Action From Day 3, Final (7/4/21) HD

Link to Day 1 video https://youtu.be/4RENlCmD_HY Link to Day 2 video https://youtu.be/sMAkuskTync While railfanning at South Fork, PA during day 2, I thought for the last full day, I will do a rather laid-back "lazy" Sunday 4th of July railfanning at this very location for a majority of the day, then switching to one or two spots back east for the remainder. I got to add two more NS heritage units seen for this stay (Norfolk & Western - NS 8103 and Reading - NS 1067, even though I have already completed the NS heritage hunt years ago). I also got to see westbound using track 1 and eastbound using track 3 (back then, track 1 is only signaled eastward & track 3 westwards between South Fork & Altoona, but sometime in 2019 all tracks are bi-directional, which helped big because not long after, westbound mixed freight 34A derailed at Horseshoe Curve, leaving only track 1 open, and trains did roll by while cleanup and track repair are underway). Back in Altoona at night, I did caught a few 4th of July fireworks while trains rolled by. Anyway, I had a great time during this much-needed railfanning trip back on the Pittsburgh Line, first time since the pandemic! Note: I did follow the line east to Harrisburg the next day on my way home but I did not record any videos.
