The Plymouth Rail Road Company was incorporated in Pennsylvania on April 18, 1836. Between 1837 and 1838, it constructed a short railroad from Corson's lime kilns near Plymouth Meeting to Conshohocken, Pa. It was operated by horse power. By the late 1850s, it was getting out of repair, but the Civil War interfered with raising sufficient funds, and it was temporarily abandoned by the early 1860s. After the war, the Plymouth Rail Road came under the control of the Philadelphia, Germantown and Norristown Railroad Company, with which it connected at Conshohocken, and in 1868-70 it was rebuilt and extended from Plymouth Meeting to Oreland. It was included in the lease of the PG&N to the Philadelphia and Reading Railroad Company, effective December 1, 1870, and remained a branch line within the Reading railroad system for a century.
