Norfolk Southern has completed a package of new strategic infrastructure investments across Alabama designed to increase freight capacity, improve network fluidity and strengthen one of the state’s most important rail corridors and a critical economic engine for the state.

The work, which began in 2024, included more than a half-dozen separate projects along Norfolk Southern’s 3B Corridor, which connects businesses and markets in northern and central Alabama with the Port of Mobile and destinations worldwide. Projects included a mix of terminal and track-based infrastructure improvements designed to support continued business and economic growth across the state. In addition to improving network capacity and flow, the work also included targeted grade crossing improvements in communities along the corridor.

• Lacey Siding Extension and Relocation | Extension of an important siding in Shelby County, as well as a westward shift of the siding’s footprint to significantly reduce blocked crossings in the nearby Brantleyville neighborhood.
