The original Blackfriars station was opened in 1864, on the south bank of the River Thames. It closed in 1886 after the opening of Blackfriars Bridge, and a new station, then called St Paul's opened on the north bank. It was renamed to Blackfriars station in 1937.
Northbound services used to go to Holborn Viaduct station, but now go to City Thameslink station.
