The Pine Grove and Lebanon Railroad was incorporated on September 27, 1868 (the first railroad incorporated under Pennsylvania's general railroad law) to build south from Pine Grove to the Lebanon County line. The Lebanon & Pine Grove Railroad (L&PG) was incorporated at about the same time to be built from the county line south to Lebanon, meeting the Reading's Lebanon Valley Branch. The new line was built in 1870, and the first train ran between Lebanon and Pine Grove on March 7, 1870. The Pine Grove & Lebanon, L&PG, Good Spring and Lorberry Creek were consolidated to form the Lebanon & Tremont Railroad (L&T) on March 25, 1871. On May 8, 1871, L&T was itself merged into the Philadelphia & Reading Railroad.
