The MTA has created a new map to help straphangers navigate regular nighttime service changes.
The agency printed 25,000 "Late-Night Maps" that show overnight changes, like regularly added and canceled service. For instance, three lines shut down after midnight, six express trains become local and an overnight shuttle runs.
"The standard subway map depicts morning to evening weekday service,” MTA chief Joseph Lhota said in a statement. “This companion night map will, for the first time, depict service for a particular portion of the day.”
The maps — which are designed with a gray background to distinguish it from the standard one — are available in Grand Central Terminal and at the transit museum.
The agency said it also plans to have a new piece of art on the back of each new overnight map. Expecting collectors, the MTA is selling unfolded copies for $20.
