In 2019, due to flood­ing caused by Hurricane Sandy, the MTA plans to start either an 18- or 36-month reha­bil­i­ta­tion project on the L train’s Canarsie Tunnel. With either con­struc­tion plan, the L train would con­tinue to oper­ate in Brooklyn, but for pas­sen­gers to trans­fer to a Manhattan-bound train, many would have to first travel in the oppo­site direc­tion. 

A way to reroute the flow of these com­muters would be to provide E train ser­vice that runs along the G line.  Currently the E train has a World Trade Center ter­mi­nus that aligns with the Chambers Street A/C tracks.  ReThink Studio pro­poses an exten­sion of the E train into Brooklyn via the exist­ing A/C tunel, then along the Court Square-bound G tracks. Adding a rail switch at the Hoyt-Schermerhorn Station will make this route pos­si­ble.  This new ser­vice would reduce the con­ges­tion on J/M/Z trains com­ing from Jamaica Center and Central Av.
