When the Southside Works was under construction, the railroad agreed to bury their rail line.
They increased the vertical clearance inside the 1,600 linear-foot-long stretch of the tracks, relocating utilities, improving drainage, and removing overhead structures near both tunnel portals.


Look how beautiful!
This might be an option to cover the trough and ‘heal the wound’ that now cuts through Allegheny Commons.
The tunnel in the photos was already there from the days when the site was a steel mill, with the green space built over it when the South Side Works was developed. The tunnel height was raised as part of a project CSX had so it oculd run double stacks through Pittsburgh. This is the Pittsburgh Subdivision of CSX, not Norfolk Southern.
Agreed. We didn’t mean to imply that it was Norfolk Southern, only that we’d like Norfolk Southern to follow CSX’s example.
