The Abandoned Coburn Railroad Tunnel, Coburn, Pennsylvania
The Coburn Tunnel, also known as the Beaver Dam Tunnel, although I don’t know why, was built between 1872 and 1877 by the Lewisburg, Centre and Spruce Creek Railroad. The tunnel is 260 feet long and named after Colonel J.P. Coburn one of the railroad directors. Unfortunately the rail line was a financial loser from the start. On December 13, 1879, the company defaulted on its bonds, and on December 31, 1879, it was reorganized as the Lewisburg and Tyrone Railroad. The new company was leased to the Pennsylvania RR the next day on January 1, 1880. In 1915 it was merged with the Pennsylvania RR. In 1970 Penn Central abandoned this portion of the line and the rails were removed the following year.
So basically as of 2021 this tunnel hasn’t seen rail traffic in over 50 years.
