CSX Transportation has completed work on a third of the double-stack freight rail corridor between mid-Atlantic seaports and the mid-west in the US with a target to complete the project by 2015.
The National Gateway is a public-private partnership that will create a double-stack freight rail corridor between mid-Atlantic sea ports and the mid-west.
The projects are designed to increase vertical clearances at 61 locations on CSX rail lines in the region to accommodate intermodal trains carrying double-stacked containers.
The National Gateway's first phase, which spans an existing rail corridor between North Baltimore, Ohio and Chambersburg, is underway.
So far work has been completed at five of the locations, and work is being carried out at 15 other locations.
The completed projects include bridges in Hyndman and Chartiers Creek, which were modified for double-stack usage.
CSX stated that it will invest an additional $160m to complete the National Gateway by 2015, coinciding with the expansion of the Panama Canal, which is expected to bring more traffic through East Coast ports.
