Pushing hard

Usually when we head out to Ohio to see our son and family, we get a father & son railfan trip. Last year was Altoona (NS F's and 4 heritage units) so this year for some reason I wanted to go to Pittsburgh. Particularly for the trench and Union RR. Many thanks to Ian Hapsias for info! We eventually found the steel mill, spent some time there and caught some action. A slab train shoves up the ramp.
