City Thameslink station opened in 1990 and was originally called St Paul’s Thameslink due to its proximity to St Paul’s Cathedral, a quarter of a mile away along Ludgate Hill. But there were concerns about it being confused with St Paul’s London Underground station on the Central line, so a year later it was renamed City Thameslink.
In the heart of the City of London's financial district, the station is one of the capital’s key commuter hubs on the Thameslink main line, which runs between Bedford and Brighton right through central London. It was upgraded in 2010, as part of improvements across the whole Thameslink network, to enable 12-car trains to call at the station. Currently ten trains per hour in each direction pass through the station at off-peak times, and at the last count, over six million passenger journeys each year start or finish at the station.
