The Tybee Railroad, also known as the Tybee Branchline, was a railroad in the United States which operated from 1887 to 1933. Originally chartered as the Savannah & Tybee Railroad, it was purchased by the much larger Central of Georgia and operated as a branch line for most of its existence. At its peak, the railroad carried a quarter million people a year, with many vacationers using the train to reach resorts on Tybee Island. The railroad was instrumental in the economic development of the island as a regional resort, and the train even earned the nickname "The Marsh Hen". The construction of US80 signaled the end of train service, and the line was abandoned in 1933.
