The MTA plans to increase subway service on two heavily trafficked lines as ridership continues to increase.

In fall 2016, riders of the 2 and 7 lines will see increased service as the city plans to add more scheduled trains during weekend and evening hours, the MTA reported.

The increased service on the 2 line will amount to an additional 31 round trips on Saturdays and 18 additional round trips on Sunday, according to the MTA.

In 2015, nearly every station on the 2 line saw increased ridership, the MTA stated, adding that maintenance work on the 5 train makes the 2 train the only subway serving some northern Bronx neighborhoods such as Williams Bridge, Baychester and Wakefield.

The 7 train’s added service will include two more round trips on weekday evenings between 8 and 10 p.m., the MTA said.

“Our biggest challenge now is juggling our record ridership demand all week long while maintaining a system that stays open 24 hours a day, seven days a week,” MTA NYC Transit President Veronique “Ronnie” Hakim was quoted in the MTA statement.

The additional service will begin implementation in the fall, and the schedule will be finalized in the coming months, the MTA added.
