Subway riders along the B, D, F and M lines are bracing for another week of repairs and changes as part of the MTA "FASTRACK" program.

Starting tonight through Friday, subway service will shut down on sections of the lines for construction from 10 p.m. to 5 a.m. Officials say overnight repairs allow crews to work more efficiently and in safer conditions.

The MTA says it has already successfully completed repairs on the 1 through 6 lines with the "FASTRACK" program .
