"This is a vital upgrade to our Red Line rail system focusing on infrastructure, drainage, rails, ties, ballast and overhead power system," said Joe Calabrese, CEO and general manager of the RTA.
Delta Railroad, Inc., will perform the S-curve work. The track curves first in one direction, then the other, as it ascends from the West 98th Street station to the West 117th Street station. This section of track is nearly 3,000 feet of the Windermere to the Airport Red Line built in 1955.
The existing track drainage system in the S-curve is not working properly. Portions of the track are constantly wet and water flows from one section of track to another. The entire drainage system must be cleaned, with certain portions needing to be replaced. A slab that supports track at the west end of the curve will also be replaced.
The retaining walls and one bridge abutment require repairs and strengthening. New rails, ties and ballast will ensure that the track is maintained, with periodic maintenance that does not interrupt service. Finally, the overhead power system will be adjusted to best align with the new tracks.
