The Penn Central rail line ran through the eastern portion of Derwent (heading south to Marietta) and which crossed the Baltimore and Ohio rail line ran immediately to the south, heading toward Cumberland, Ohio and which eventually terminated at the Muskingum Electric Railroad.

Byesville Scenic Railway is a tourist railroad located in Byesville, Ohio. Service was suspended in 2011, and as of late 2021 has not resumed. The railway is a non-profit group dedicated to preserving the local coal mining and railroad history in Guernsey County, Ohio, United States. The railroad runs on track that was originally known as the Cleveland & Marietta Railroad and later became part of the Pennsylvania Railroad. The primary freight hauled was coal, as Guernsey County was a large producer of coal. It later became part of the Penn Central Railroad due to a merger of the Pennsylvania and New York Central and later Conrail. In the early 1980s most of the C&M was removed, the remaining portion from Cambridge to C&M Junction (just south of Derwent) was sold to the Chessie System (which later became CSX Transportation). Guernsey County purchased Byesville to C&M Junction in 1999 which lay dormant until 2003 when the Buckeye Central Scenic Railroad began operating a tourist train from Byesville, Ohio to Derwent. In 2006, the newly formed Byesville Scenic Railway (BSRW) began operations and has continued the rehabilitation of line to C&M Junction.
