The entire Concourse Line opened on July 1, 1933,<ref name="BklynEagle-INDCncrseOpen-1933">{{cite news|title=Bronx-Concourse New Subway Link Opened at 12:57 A.M.: Adds 21 1/2 Miles to City's System−Connects With Manhattan Line at 145th|url=https://www.newspapers.com/clip/30303616/the-brooklyn-daily-eagle/|via=[[Newspapers.com]]|work=The Brooklyn Daily Eagle|access-date=October 26, 2015|page=20|date=July 1, 1933}} {{open access}}</ref><ref name="NYTimes-INDCncrseOpen-1933">{{cite news|url=https://www.nytimes.com/1933/07/01/archives/new-bronx-subway-starts-operation-40000000-branch-of-city-system.html|title=New Bronx Subway Starts Operation|date=July 1, 1933|newspaper=The New York Times|access-date=February 13, 2010}}</ref> less than ten months after the IND's first line, the [[IND Eighth Avenue Line]], opened for service. Initial service was provided by the [[C (New York City Subway service)|C]] train, at that time an express train, between 205th Street, then via the Eighth Avenue Line, [[Cranberry Street Tunnel]] and the IND South Brooklyn Line (now [[IND Culver Line|Culver Line]]) to [[Bergen Street (IND Culver Line)|Bergen Street]].<ref name="NYTimes-INDCncrseOpen-1933" /> The CC provided local service between [[Bedford Park Boulevard (IND Concourse Line)|Bedford Park Boulevard]] and [[Hudson Terminal (IND Eighth Avenue Line)|Hudson Terminal]] (now World Trade Center).<ref name="NYTimes-INDCncrseOpen-1933" /> Trains initially ran every 4 minutes during rush hours, every 5 minutes during the daytime off-peak, and every 12 minutes at night. The timetable called for 92 express trains and 247 local trains a day.<ref name="nyt-1933-06-18" /><ref name="p1114759078" /> In addition to peak-direction express service (southbound in the morning and northbound in the afternoon), there was a "theater express" service, which ran southbound toward the [[Theater District, Manhattan|Theater District]] for about half an hour during the evening.<ref name="nyt-1933-06-18" />

On December 15, 1940, with the opening of the [[IND Sixth Avenue Line]], the [[D (New York City Subway service)|D]] train began serving the IND Concourse Line along with the C and CC. It made express stops in peak during rush hours and Saturdays and local stops at all other times. C express service was discontinued in 1949-51, but the C designation was reinstated in 1985 when the use of double letters to indicate local service was discontinued. During this time, the D made local stops along the Concourse Line at all times except rush hours, when the C ran local to Bedford Park Boulevard. On March 1, 1998, the [[B (New York City Subway service)|B]] train replaced the C as the rush-hour local on the Concourse Line, with the C moving to the Washington Heights portion of the Eighth Avenue Line.<ref name=NYCDCP-BwayJctStudy-2008>{{cite web|title=Broadway Junction Transportation Study: NYC Department of City Planning Final Report-November 2008 |url=http://www.nyc.gov/html/dcp/pdf/transportation/broadway_junction_complete.pdf |website=[[Government of New York City|nyc.gov]] |publisher=[[New York City Department of City Planning]] |access-date=October 27, 2015 |date=November 2008 |url-status=dead |archive-url=https://web.archive.org/web/20100606140932/http://www.nyc.gov/html/dcp/pdf/transportation/broadway_junction_complete.pdf |archive-date=June 6, 2010 |df=mdy-all }}</ref>

In June 2022, the MTA announced that the express track would be closed starting that July, with D trains using the local tracks at all times until the end of 2022. The closure would allow the MTA to conduct structural repairs to the line, including steel and concrete work; the project was to be completed in September 2024.<ref name="Mass Transit 2022">{{cite web | title=MTA to begin next phase of concourse line reconstruction on B and D Lines in the Bronx |date=June 13, 2022 | website=Mass Transit Magazine | url=https://www.masstransitmag.com/rail/maintenance/press-release/21270838/mta-new-york-city-transit-mta-to-begin-next-phase-of-concourse-line-reconstruction-on-b-and-d-lines-in-the-bronx | access-date=July 1, 2022}}</ref><ref name="Rivoli 2022">{{cite web | last=Rivoli | first=Dan | title=MTA to 'refresh' Grand Concourse stations during rehab work | website=Spectrum News NY1 New York City | date=June 28, 2022 | url=https://www.ny1.com/nyc/all-boroughs/transit/2022/06/29/mta-grand-concourse-stations-rehab-work | access-date=July 1, 2022}}</ref> During that time, the line would also be closed for 40 weekends, and there would be overnight work for 75 weeks.
