For straphangers wondering which subway lines will beef up service to carry runoff from the looming L train shutdown, New York City Transit has just provided a list.

It includes the 7 line, which will make 14 more round-trips per day, as well as the G train, which will be making 66 more to help commuters get to the 7 train for the trip across the East River. (The changes to the 7 line were previously announced.) There will also be 62 round-trips added daily to the M line, which will start extending its route on weeknights to the new station at 96th Street and Second Avenue.

The J/Z will make 16 additional round-trips, the E will make 26, the F will make 12 and the A will make 2.

Altogether more than 1,000 round-trips will be added to those seven subway lines to try to accommodate some of the 225,000 commuters who currently ride the L train back and forth between Brooklyn and Manhattan. The Canarsie Tunnel, which carries the L between the two boroughs beneath the East River and was damaged during Superstorm Sandy, will be closed in April for repairs for an expected 15 months.

The 7 line between Queens and Manhattan has been shut down recently on weekends because the city is getting ready to push its service to its limits. Other lines as well are now undergoing repairs, a sign that things will only get worse before they get...worse.

"The tunnel reconstruction project will be the most impactful Superstorm Sandy-repair work we will undertake, and as such, we must ensure we have viable, reliable alternatives, particularly on the subways where we can accommodate the largest number of riders," said Andy Byford, the Transit Authority's new president. "We will be adding more than a thousand round-trips each week and pushing our resources to capacity, which is also why you're seeing so much preventative maintenance and repair work on all these lines already. We are making these lines as reliable as possible for these new service levels starting in 2019."
