Overview
- CSX resumed train movements through the enlarged tunnel on Sept. 26, with officials saying the project finished ahead of schedule and on budget.
- Regular double-stacked intermodal trains are slated to start after remaining bridge clearances between Baltimore and Philadelphia are completed, which is expected in early 2026.
- The public–private financing totals more than $450 million, with Maryland committing over $200 million, a federal grant of about $125 million, CSX contributing roughly $140 million, and a smaller share from Pennsylvania.
- Crews excavated and lowered the railbed to gain clearance, and CSX opted for a full closure that diverted roughly 16 daily trains to longer routes, saving about $48 million and shortening construction time.
- CSX and public officials say the upgrade will shift more freight to rail and strengthen the Port of Baltimore, with the company projecting about 160,000 additional containers a year and more than 13,000 jobs once full double-stack service begins.
