The Central Pennsylvania Railroad was incorporated on May 11, 1889 to connect Unionville with Mill Hall, running by way of Bellefonte and the Nittany Valley. On December 11, 1890, the Central Pennsylvania Railroad Eastern Extension was incorporated, to leave the main line of the first company at Lamar and follow Fishing Creek, Sand Spring Run, and White Deer Creek to White Deer on the Susquehanna. This would provide a connection to the Philadelphia and Reading Railway, in addition to that with the NYC at Mill Hall.
