B train to go express again after 2 years of renovations

B train riders rejoice — your commute gets a whole lot better starting Monday.

After two years of renovations, express service along the B line returns today, saving an average of 125,000 riders up to six minutes every day, according to the MTA.

The train will skip all local stations and stop only at Brighton Beach, Sheepshead Bay, Kings Highway, Newkirk Plaza, Church Avenue and Prospect Park.
