Much has changed at the summit of the Allegheny Divide in 22 years.

In the 1990s Conrail enlarged the tunnel clearances on one tunnel and added a second track while abandoning an adjacent bore. Conrail operations were conveyed to Norfolk Southern in 1999, and a new bridge was built over the tracks.

Last month on our visit to the Tunnel Inn at Gallitzin, Pennsylvania, I made a variety of photos of Norfolk Southern trains passing through the tunnel.

I thought it would be neat to pair these helper images with vintage photos of Conrail trains from approximately the same location that I made on Kodachrome 25 back in July 1989.
