After a year of repairs, normal weekend service returned to the 2 and 3 train lines Sunday.

For the past year, commuters could not take the 2 or 3 train in Brooklyn on the weekends.

The MTA has been fixing the Clark Street Tunnel since June 2017, after it was damaged by storm surge flooding during Hurricane Sandy in 2012.

The 98-year-old tunnel carries 2 and 3 subway trains under the East River between Clark St. in Brooklyn and Wall St. in lower Manhattan.

New track and signal cables were installed, as well as fire protection systems.

The repairs also included resiliency measures aimed at helping minimize flood risks in future storms.
