Thanks guys for rediscovering this thread.

I lament a bit that I don't have that job anymore, and I don't get out there like I used to. (But I like what I'm doing now!

)
Anyway, one place I REALLY wanted to get pics of was the Steel Plant south of the City of Harrisburg, as there's still lots of PRR infrastructure, and the Mill itself is just fascinating. It has a rail mill there, and you can usually see rail trains sitting in there, along with lots of the older parts of the facility still standing.
There's a rail line that runs on the west side of the river going south that sees lots of unit coal trains (funny as they go past Three Mile Island...

) And the Triple Crown Yard and Intermodal facility with the remote GP-38's up off I-83 not too far from the PA Greenstamp is fascinating stuff as well.
A person could spend a week in that town and not get to see all the great train stuff there. And I didn't mention the Rockville Viaduct, the Harrisburg Train Station, or any of the other landmark places!! It's a train lover's paradise, and it's also not that far away from Altoona!
