I heard that there is a decent place train to watch and photograph trains along the CSX and NS main lines in North East PA. Planning on taking a "day trip" to that location (from Buffalo) soon. Has anyone been their? advice or comments? Thanks.
The old New York Central depot in Northeast is now home to the Lakeshore Railway Historical Society. There's a collection of equipment, including some locomotives built in nearby Erie by GE and Heisler, as well as other locomotives and rolling stock.
The museum is adjacent to the CSX (Former Conrail, PennCentral and New York Central) main line and the Norfolk Southern (Former Nickel Plate Road) runs just to the south, within viewing distance.

I'm originally from that area and did a lot of railfanning there a few decades ago. You might also want to check out the beautifully restored NYC depot in Westfield, NY where the Jamestown, Westfield and Northwestern, the last interurban in New York State, made connections with NYC passenger trains until 1948. You can still make out the JW&NW tracks to the west of the station. The NS is in very close proximity here as well.
A little further to the west, in Ripley, NY just before the Pennsylvania state line, there is a stretch where CSX and NS parallel in very close proximity. There are some crossings there that provide a good viewing area between the two main lines.
