History of The Old Tunnel State Park
After the Civil War, German immigrants in Fredericksburg wanted a faster way to transport their goods and products to the San Antonio Marketplace some 70 miles South. The Fredericksburg and Northern Railway was built in the early 1900s to connect Fredericksburg to the existing San Antonio and Aransas Pass railway.
During the construction, a 920-foot tunnel was built in a hill halfway between Fredericksburg and the town of Comfort, Texas. The first trains began running on the newly constructed Fredericksburg and Northern Railway line in 1913 and continued until WWII, when the railway was deconstructed and sold for scrap.
