The northern portion of the Lebanon & Tremont came from the
Good Spring Railroad, which was incorporated in 1861 or 1863, but was not organized until March 26, 1869. It was controlled by the
Reading Company (RDG) which transferred to it the property of the Swatara Railroad in 1863, giving it a line from Lorberry Junction to
Donaldson via
Tremont. In 1868, it was extended from Donaldson to Brookside. At Lorberry Junction, the Good Spring connected with the former
Union Canal and the
Lorberry Creek railroads, the former of which ran south to the Union Canal and the Schuylkill & Susquehanna Railroad at
Pine Grove. All were by now owned by RDG. While coal originating on these railroads could be hauled laterally east and west over the Schuylkill and Susquehanna from Pine Grove, or west on the Mine Hill and Schuylkill Haven Railroad from Tremont, there was no direct route southward. To remedy this, the RDG chartered two new roads. 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. ==Main and branch lines==
