Project Description 

RailWorks undercut the track in eight locations along the line to increase the clearance.

Project Scope 

Tracks were removed in sections to allow removal of ballast and subgrade to lower the main line under select, grade-separated highway overpasses. Each location required removing and reinstalling 400 to 1,300 feet of track to establish the newly designed grades. Track was generally lowered 6 inches at the low point under each overpass.

Access was usually difficult, as the underpasses had very little working room to spare. Track was dismantled in panels, hauled out, then hauled back in, set on the new grade and reconnected. Defective ties were replaced as needed.

Ditch lines were also restored or improved in each area worked to promote positive drainage with the new track grade. RailWorks then installed the ballast and surfaced the track, and welded the rail when required.

Unique Features 

Work was generally completed over extended weekend outages.
