The only service to use the Crosstown Line is the {{NYCS|G}}. The line north of [[Court Square (IND Crosstown Line)|Court Square]] has not been in regular use since 2010.<ref name="tracks2">{{NYCS const|trackref|trackbook3}}</ref>

The north end of the Crosstown Line is a [[flying junction]] with the [[IND Queens Boulevard Line]] and [[60th Street Tunnel Connection]] just south of [[Queens Plaza (IND Queens Boulevard Line)|Queens Plaza]]. The line then travels south as a two-track line, except for a center relay track south of Court Square. At the turn from Marcy Avenue to Lafayette Avenue, two center tracks appear, merging into one after crossovers to the main tracks. These tracks were to be used for a split to another line in [[Proposed New York City Subway expansion (1929–1940)|a 1931 expansion plan]]. This center track continues through [[Bedford–Nostrand Avenues (IND Crosstown Line)|Bedford–Nostrand Avenues]] and then ends with crossovers to the main tracks, but space remains in the center through [[Classon Avenue (IND Crosstown Line)|Classon Avenue]] for the third track.<ref name="tracks2" />

At [[Hoyt–Schermerhorn Streets (IND Crosstown Line)|Hoyt–Schermerhorn Streets]], the Crosstown Line passes through the middle of the four-track [[IND Fulton Street Line]]. [[Cross-platform interchange]] is available between the lines, but no track connections exist. After Hoyt–Schermerhorn Streets, the line turns south and ends as a merge into the local tracks of the [[IND Culver Line]], just south of the split of that line into local and express tracks.<ref name="tracks2" />
