From the 1920s onward, more and more work was relocated from Renovo to Altoona, but Renovo continued as a significant repair and car-building facility through World War II.

After the dissolution of the PRR into Conrail, parts of the railroad west of Emporium were sold off to other entities before being reunited under the Allegheny Railroad; subsequent mergers resulted in the road now being a branch the Buffalo and Pittsburgh Railroad, with the exception of an abandoned portion from St. Marys to Emporium. East of Emporium, the road is now part of the main line of Norfolk Southern from Harrisburg to Buffalo.
