CSX National Gateway Initiative, Phase 2

CSX National Gateway Initiative, Phase 2 is the reconstruction of 11 locations along a Class I freight railroad to accommodate the use of double-stack trains. Each location has different clearance improvements along 92 miles of track from Jessup, MD, through Washington, DC, and west to Martinsburg, WV. The approach involves lowering and realigning tracks, raising bridges, and blasting and relining tunnel crowns to clear trackway.
