The purpose of this project is to add a third mainline track from Enola to Cove PA, preserving the continuous movement of new Amtrak passenger trains through the busy Harrisburg/Enola area. In addition to a third mainline track, this project will also realign multiple mainline and yard tracks, construct one new railroad interlocking, reconfigure existing interlockings, upgrade culverts and drainage pipes under the railroad, modify structures as needed, and improve existing railroad grade crossings.
Construction for this project began in January of 2026, and construction is anticipated to be completed in October of 2027. Work activities will primarily be completed during daylight hours. The daily Pennsylvanian train service will remain in operation during work activities.
The work will be completed both by Norfolk Southern forces and Third-Party Contractors.
Site preparation work, including access road construction, has been completed in the First Quarter of 2026. Utility relocations and new drainage installation along the right-of-way have begun, and this work will continue throughout 2026. The majority of the roadbed for the new third main track has been installed between the Rockville Bridge and Cove, PA, and construction of the track will begin later in 2026. Structural work in the area of "CP Mary" began in the Second Quarter of 2026, which includes micropile and drilled shaft installation to support construction of the third mainline.
The required signal prep work and modifications by Norfolk Southern forces is in progress. Track work performed by Norfolk Southern forces has also begun near CP Mary, focusing on Tracks D and G at the north end of Enola Yard.
