After this weekend’s miraculous temporary return of the L train, the MTA’s said the L train will be out of service between Lorimer and Myrtle-Wyckoff for at least another two weekends, meaning more crowded shuttle buses for residents — and more lost business for stores, restaurants and galleries.

Art galleries typically roll out new shows in September and are often only open on the weekends, when trains have been shut down, said Deborah Brown, the owner of the Storefront Bushwick gallery at 16 Wilson Ave.

“It’s really disheartening to see that a lot of people are not going to be able to get to us easily during the first six weeks of the art season when all the excitement is,” she said. Storefront Bushwick still saw good traffic after getting a positive review in The New York Times, but might have had even more if trains were running, Brown said. ”It put a huge burden on people to figure out how to get there,” and other galleries had also reported getting fewer visitors, she said.
