On 1 January 1866, LC&DR and GNR joint services from
Blackfriars Bridge began operating on to the Met via the
Snow Hill tunnel under Smithfield market to Farringdon and northwards on to the GNR. From 3 January 1866 GNR services ran to Ludgate Hill and LC&DR services ran to Farringdon Street. The Midland Railway junction opened on 13 July 1868 when services ran into Moorgate Street before St Pancras station opened. The line left the Midland main line at St Paul's Road Junction, entering a double-track tunnel and joining the Widened Lines at Midland Junction. A tunnel was built west of Midland Junction with the intent of quadrupling all the way to Paddington, but was not used until 1926. Initially services ran from the Tottenham & Hampstead Junction line to Moorgate and Victoria. From 1 July 1875 the Midland ran services from and to Victoria, the LC&DR between Victoria and Hendon. On 1 September 1871, an eastern curve from the Snow Hill line was opened and the LC&DR diverted its Victoria to Farringdon service to Moorgate. This started at 80 trains per day, declining to 48 by 1913. The
South Eastern Railway (SER) built a connection with the LC&DR at
Blackfriars Bridge. From 1 June 1878, the GNR ran six trains a day to and from 1 August 1880 the SER ran to Enfield and on behalf of the GNR. The writer Andrew Martin claims that, by the end of the 19th century, a continental passenger service linked
Liverpool with
Paris via the Widened Lines. Trains departed at 08:00 and arrived in Paris by 22:50, the passengers having transferred at
Folkestone to a steamer across the
Channel. In the early 20th century, competition from the electric underground railways and electric trams meant that the SER and GNR service was withdrawn on 30 April 1907, the GNR and LCDR service in September 1907 and the Midland and LCDR service in June 1908. Passenger services across London through
Snow Hill railway station and Snow Hill tunnel were withdrawn in 1916. From 1 January 1908, electric locomotives were exchanged for steam locomotives on passenger trains at Paddington, and GWR services continued to run until 1939. The former GNR and Midland services continued to run to Moorgate,
DMUs and diesel locomotives replacing steam in the 1960s. In 1976 the former GNR services were diverted at via the
Northern City Line to Moorgate, and York Road station and the curves into King's Cross closed. In 1978, work started on electrification of the Widened Lines from St Pancras to Moorgate as part of the "Bedpan" line, an electric service between
Bedford and Moorgate, opening on 15 July 1983. King's Cross Widened Lines station was renamed King's Cross Midland City, and
King's Cross Thameslink in May 1988 when the Snow Hill tunnels reopened for
Thameslink. The line from Farringdon to Moorgate closed on 20 March 2009, to allow the platforms at Farringdon to be extended to take 12-car trains. ==LC&DR stations==
