Fastrack repairs will effect overnight service of F and G trains in Brooklyn this week.

F and G trains will not make stops between the Bergen St. and Fort Hamilton Parkway stations from 10 p.m. and 5 a.m. between Monday night, May 16, and early Friday morning, May 20.

The MTA will have F trains running express between Jay St-MetroTech and Church Ave. in both directions, stopping at 7 Ave. G-train service will operate in two sections: between Court Square and Bedford-Nostrand Aves., and between Bedford-Nostrand Aves. and Hoyt-Schermerhorn Sts.

MTA will run free shuttle buses between Jay St.-MetroTech and Church Ave. Buses will make all stops at Bergen St., Carroll St., Smith-9 Sts., 4 Av-9 St., 7 Ave., 15 St.-Prospect Park and Fort Hamilton Parkway.

To avoid the work, commuters can transfer between G and A trains at Hoyt-Schermerhorn Sts. Or, transfer between the F and A trains at Jay St-MetroTech.

The next Fastrack repair is also scheduled for the G train during two consecutive weeks in June.
