This abandoned railway line was originally started by the Brunswick and Birmingham Railway, which was formed in 1900 with the intent to connect its namesake towns. After building the initial segment of the line between Brunswick and Offerman in 1903, the B&B was soon bought out by the Atlantic & Birmingham Railway, and construction continued. The line went through several owners over the next few years, and was extended to Manchester in 1908 (just a little over halfway between Brunswick and Birmingham). The line eventually came under the control of the Atlantic Coast Line in 1926, with complete ownership coming 20 years later as the ACL's Western Division. By this time, the line had been extended through Alma and reached as far as Nicholls. However, the line from Brunswick to Alma was abandoned in 1953, while the remainder of the line (Alma to Nicholls) was purchased by the Seaboard Coast Line, and was finally owned by CSX. Abandonment of that segment came in 1986.
Today, most of the right-of-way serves as a power line corridor that stretches from Brunswick to Alma. A few mileposts remain to mark the line; a majority of these are from the days of the Brunswick and Birmingham Railway.
Suzy adds: I've also heard a story that a train once broke down on a trestle over a swamp/creek west of Brunswick in 1920 and that it took 3 days for rescue to reach the train. I don't have any press clippings to prove if this story is true. I do have pics of the old trestle though.
Thanks to Suzy Krone for contributing information about this route.
