Grand Central Train Shed Roof Replacement

Brief, fair-use quote:

Replacement of enormous train yard's roof will require ripping up Midtown streets immediately above it

The train shed, which comprises two levels of tracks used to stage and store Metro-North cars, is underground roughly between Lexington and Madison avenues and has a footprint larger than 20 football fields. The shed runs north of Grand Central to East 50th Street before tapering down to the width of Park Avenue and ending at East 57th Street. It was built with the terminal in 1913, and it has greatly deteriorated from water leaking onto its roof and support structures.

The MTA told elected officials and stakeholders on a conference call last week that maintenance will be insufficient to keep the shed's roof in working condition, and that Metro-North has opted to replace it completely, multiple sources with knowledge of the call said. Because of the complexity of the job—trains will run throughout the construction—officials are planning a pilot project along Park Avenue between East 53rd and East 55th streets to learn how larger and more complex phases might be best handled.

The MTA envisions the pilot project will cost around $250 million and begin in 2021 or 2022—although that could change, as the agency's big projects often do. The plan is still in its infancy.

The MTA recently purchased Grand Central Terminal for $35 million, a deal which gave the agency more control over development projects happening at the landmark. And in one of their first orders of business, it looks like they’re mulling a massive undertaking to replace the train shed roof, according to Crain’s sources. The shed is a two-level-deep underground space comprised of tracks, bridges, and viaducts used to stage and store Metro-North cars. It runs north of the terminal to East 57th Street and takes up an area larger than 20 football fields. Not only would the project cost hundreds of millions of dollars and take 20 years to complete, but Crain’s notes that it would likely result in many Midtown streets being ripped up.


The train shed was built along with the terminal in 1913, but over the last century, it’s rusted and deteriorated from water leaking onto its roof and supports. For many years, the state has made repairs on an as-needed basis, but according to Crain’s, “The MTA told elected officials and stakeholders on a conference call last week that maintenance will be insufficient to keep the shed’s roof in working condition, and that Metro-North has opted to replace it completely.”
