The most common maps of Penn Station's interior are ephemeral, and are usually found on MTA fliers and posters. They are designed to guide commuters to their trains and to exit the station, but rarely provide spatial orientation to the station as a whole or to the outside environment of the city. In its current configuration, Penn is divided into three "zones" for its three railroad services - Amtrak, Long Island Railroad, and New Jersey Transit. Map ephemera generally details one of these areas, without providing context to the rest of the station.

Below are examples of map ephemera relating to Penn Station.

1960's Station Pamphlet 
Produced by the LIRR, this pamphlet was designed to help commuters navigate the changes to Penn during the demolition of the old station and the layout of the new station. It is also a rare piece of ephemera which provides a map of the entire station. This map can be used to track changes to the station's layout since the 1960s.
