RAILROAD EMBANKMENT STABILIZATION

STABLE ON TRACK, STEADY ON TIME

For Metro North Railroad, we were able to solve a decades old problem of railroad embankment erosion that was causing delays and maintenance for rider safety. The custom solutions we developed put the tracks on solid ground for the long term. We were also able to develop and implement some groundbreaking (pun intended) concepts that can be applied to similar areas along the Hudson River Line.

RAILROAD EMBANKMENT STABILIZATION

Forty-four miles north of Grand Central Terminal and between a narrow section of a mountain side and the Hudson River, tracks carry daily commuters into New York City via Metro-North and Amtrak. Shored up over the years by short-term temporary fixes, Metro-North Railroad brought us in to examine and provide long-term solutions to slope loss and service interruption.

Over the decades ago, steel boom truss structures were placed as temporary support at the face of the shoreline slope. The steel boom was held with buried cables horizontally anchored into bedrock. The last boom was placed circa 1990 as a shoreline replacement for an earlier one that failed and was lost into the river and the final temporary boom deteriorated, providing a diminishing benefit to the stability of the embankment.

We collected new field information and performed analyses to better understand the nature of the instability, screened various concepts for slope stabilization, and — working closely with Metro North engineers — selected and developed a final design.
