Whenever television and films need to film in a subway station, the MTA allows them to use one of two stations generally: the lower level of Bowery which is decommissioned and has no trains coming through or Church Avenue in Brooklyn. Then, the set designers get creative with the signage to help indicate where this station is supposed to be.
In the opening of the second episode, when Jayson and Owen go busking in the subway near Grand Army High School, the subway station is meant to be the Grand Army Plaza Station on the 2/3 subway lines. In reality, this is filmed on the upper level of the Church Avenue subway station with the signage changed to show the 2 and 3 lines.
