BROOKLYN - Overnight service changes this week could throw a wrench in your commute. 

The MTA says there will be no N or R trains running between 10 p.m. and 5 a.m. for repair work between Sunset Park and Bay Ridge, and Sunset Park and Coney Island. 

Late-night and early morning riders will not be able to catch the N train between 36th Street and 8th Avenue. They also won't see an R train between 36th and 95th streets. 

A shuttle train will run between 8th Avenue and Stillwell Avenue, and a shuttle bus will make all the same train stops between 36th and 95th streets.
