Blackfriars, also known as London Blackfriars, is a central London railway station and connected London Underground station in the City of London. It provides Thameslink services: local, and regional and limited Southeastern commuter services to South East London and Kent. Its platforms span the River Thames, the only station in London to do so, along the length of Blackfriars Railway Bridge, a short distance downstream from Blackfriars Bridge. There are two station entrances – one on each side of the Thames – along with a connection to the London Underground District and Circle lines.
