The station opened on September 10, 1932, as part of the city-operated Independent Subway System 's initial segment, the Eighth Avenue Line between Chambers Street and 207th Street. Under the 2015–2019 MTA Capital Plan, the station, along with thirty-two other New York City Subway stations, underwent a complete overhaul as part of the Enhanced Station Initiative. Updates included cellular service, Wi-Fi, charging stations, improved signage, and improved station lighting. Unlike other stations that were renovated under the initiative, 34th Street–Penn Station was not completely closed during construction. In January 2018, the NYCT and Bus Committee recommended that Judlau Contracting receive the $125 million contract for the renovations of 57th and 23rd Streets on the IND Sixth Avenue Line; 28th Street on the IRT Lexington Avenue Line, and 34th Street–Penn Station on the IRT Broadway–Seventh Avenue Line and IND Eighth Avenue Line. However, the MTA Board temporarily deferred the vote for these packages after city representatives refused to vote to award the contracts. The contract was put back for a vote in February, where it was ultimately approved. These improvements were substantially completed by May 2019.
Station layout
There are four tracks, two side platforms, and one island platform. Atlantic Avenue–Barclays Center on the IRT Eastern Parkway Line and 34th Street–Penn Station on the IRT Broadway–Seventh Avenue Line are the only other stations in the system with this configuration. There is no free transfer between this station and the station of the same name on the IRT Broadway-Seventh Avenue Line, despite the fact that both connect to Penn Station. The nearest transfer location is at 42nd Street–Port Authority Bus Terminal with a free transfer to Times Square–42nd Street. South of the station, an additional track begins at a bumper block between the two express tracks with a connection to both at both ends. This allows for various extra movements of trains including storage or removal of a train with mechanical problems to be sent back in the other direction. It could also be used if 34th Street functioned as a terminal station. Like other subway stations, 34th Street–Penn Station includes black-and-white "sighting boards" for conductors to point and call, thereby indicating to the motorman that the train has stopped at the right position. On the downtown express platform, there is a blue-and-white sighting board for the R110B, a now-retired prototype New Technology Train whose conductor's cab was not aligned with any other fleet's conductors' cabs. This board is still extant and is one of a few publicly visible remnants of the R110B's operation.

The northbound platform has one street stair to each eastern corner of 34th Street and Eighth Avenue.
