However, it retained its corporate existence for some time, acquiring branch lines into the Snowshoe coal region and an extension from Bellefonte to Lemont before being merged into the PRR in 1908.
The PRR took over operation from the B&SS on January 20, 1863, and formally leased the Bald Eagle Valley on July 1, 1864.
Like the Tyrone and Clearfield, it brought coal traffic (mostly from the Snowshoe mines) into Tyrone, but it also tapped the iron furnaces of Bellefonte, and served as an alternate connection between the PRR main line and their Philadelphia and Erie subsidiary at Lock Haven.
While fully under PRR control, the Bald Eagle Valley maintained its corporate existence for some time.
Several spurs were built off the Snow-Shoe Branch in 1890 and 1903 by the Bald Eagle Valley before it was merged into the PRR on March 31, 1908.
