Mayor Zohran Mamdani signaled on Wednesday that his administration is taking a serious look at advocates’ renewed push to extend G train service to Forest Hills on weekends for the first time in 15 years — even though the MTA, and not the city, has the final call on whether that will happen.

“It’s a very interesting idea, and one we’re digging into right now,” Mamdani said of the proposal during a Feb. 11 state budget hearing in Albany. His comments came in response to a question from Assembly Member and Congressional candidate Claire Valdez (D-Queens) — one of his close allies.
