[3][4] The route of the Concourse Line was approved to Bedford Park Boulevard on June 12, 1925 by the New York City Board of Transportation.

[9] Fordham Road has more space than any other station on the Concourse Line, as it contains numerous closed stairs and passageways.

[10] The split portion of the southbound platform once had a passageway from the northernmost staircase at the Fordham Road side from the middle track to the local one.

[11] Due to security concerns, it was permanently cordoned off by a wall and employee-only door as early as April 1998.

[13] Prussian blue I-beam columns run along the platforms at regular intervals, alternating ones having the standard black station name plate with white lettering.

It has two street stairs, both at the east side of Fordham and Concourse; a long ramping passageway leads to the northernmost of these two staircases.

In 1989, the MTA proposed closing off the free zone passageway on the west side and convert the northwestern and southwestern entrances to exit only; formerly, they were only open from 6 a.m. to 9 p.m.

[24] In 1993, riders wanted the western entrances reopened as they would have been safer and more convenient for shoppers going to the Fordham stores.
