Here are two more videos from my November 2005 trip to Pittsburgh.
The first is another Norfolk Southern train in Harmar, Pennsylvania outside Pittsburgh (blog post). This one features three NS engines pulling a general freight train.
The second was taken near downtown Pittsburgh on December 1. I decided to railfan the CSX line rather than Norfolk Southern... probably a mistake if I was looking for number of trains, as the adjacent NS line had probably twice the number of trains. Oh well, it was interesting to see something different than NS and I did get the downtown Pittsburgh skyline in the shot.
