  Trains will Operate in Two Sections Five Consecutive Weekends Starting Jan. 23

 

Riders Encouraged to Use    Trains in the Bronx or Metro-North Railroad for Weekend Travel Between the Bronx and Manhattan

 

The Metropolitan Transportation Authority (MTA) today announced planned service changes on the   and   subway lines to support essential track switch replacement work between the Bronx and Manhattan. MTA crews will replace 37-year-old switches that help move trains safely and reliably between the two boroughs, with the new switches expected to provide reliable service for the next 20 years.

This state of good repair work is critical to maintaining reliable service on one of the busiest subway lines in the system and will help reduce future delays and service disruptions. The work will improve daily trips for approximately 1.1 million riders and requires extended weekend and overnight service changes, along with limited weekday impacts, from January through February.

Riders can expect the following service changes:

Late Nights and Weekend Service Changes

As of Monday, Jan. 5, and until Friday, Feb. 20, from approximately 11:45 p.m. to 5:00 a.m.,   trains are operating in two sections:

  • Between Woodlawn and 149 St–Grand Concourse in the Bronx.
  • Between 3 Av–138 St   in the Bronx and New Lots Av in Brooklyn — making all local stops in Manhattan.

These same service changes will be in effect on the   line for five consecutive weekends between Jan. 23 and Feb. 23 from approximately 9:45 p.m. on Fridays until 5:00 a.m. Mondays, extended to 5:00 a.m. Tuesday following Presidents’ Day weekend.

During these weekend service changes,   trains will operate as a shuttle in the Bronx between Eastchester–Dyre Av and E 180 St.

Travel Alternatives

While the service changes are in effect, free shuttle bus service will operate between 149 St–Grand Concourse and 3 Av–138 St  .

Riders are encouraged to consider taking the   or   train or Metro-North Railroad’s Hudson or Harlem lines in the Bronx, where subway fares will be cross-honored.

Some Weekday Changes to Keep in Mind

While most   and   trains will operate their normal weekday routes, some rush hour   trains will be rerouted to 3 Av–138 St  , and some rush hour   trains will operate on the   line between 149 St–Grand Concourse and Nevins St. These changes are expected to occur between Monday, Jan. 26, and Friday, Feb. 20.
