Anyone happen to have a listing of all the mezzanine ID codes within the system (Ex. Smithsonian Mall exit is mezzanine XX)
Major, minor. major mezzanine is the mezzanine with the elevator entrance. So Smithsonian Mall entrance would be D02 Minor.
In stations with more then one elevator entrance the major mezzanine is the mezzanine that had the elevator entrances when the station first opened. Examples, North mezzanines at Huntington and Friendship Heights, south mezzanines at National Airport and King Street.
Metro Center, Gallery Place and L'Enfant Plaza have two major mezzanines:
Metro Center north and east. North is on the C route so it would be C01 Major, east is on the A route so it would be A01 Major.
Gallery Place north and east. North is on the F route so it would be F01 Major, east is on the B route so it would be B01 Major.
L'Enfant Plaza north and east. North is on the F route so it would be F03 Major, east is on the D route so it would be D03 Major.
In station with only one entrance said entrance is also identified as the Major mezzanine.
Also a list of radio ID for terminal supervisors would be a great bonus.
