An underground station to serve Euston station was first proposed by the Hampstead, St Pancras & Charing Cross Railway in 1891. The company planned a route to run from Heath Street in Hampstead to Strand in Charing Cross with a branch diverging from the main route to run under Drummond Street to serve Euston, St Pancras and King's Cross stations. Following parliamentary review of the proposals and a change in name to the Charing Cross, Euston and Hampstead Railway (CCE&HR), permission was granted for the route in 1893, although the branch line was only permitted as far as Euston. Plans for the route that eventually became the Victoria line date from the 1940s. A proposal for a new underground railway line linking north-east London with the centre was included in the County of London Plan in 1943. Between 1946 and 1954, a series of routes were proposed by different transport authorities to connect various places in south and north or north-east London. Each of these connected the three mainline termini at King's Cross, Euston and Victoria. A route was approved in 1955 with future extensions to be decided later, though funding for the construction was not approved by the government until 1962.
In conjunction with the reconstruction of the mainline station above, a new ticket hall was excavated below the concourse with two sets of escalators replacing the lifts. The escalators provide access to and from an intermediate passenger circulation level, which gives access to the Northern line Charing Cross branch platforms and two further sets of escalators; one set each serving the northbound and southbound Victoria and Northern line Bank branch platforms. Interchanges between the northbound and southbound Victoria and Northern Bank Line platforms are made via a passageway at the lower level so as to avoid the need to use the escalators. An emergency stair to the intermediate interchange level is located midway along the passageway. The Victoria line platforms opened on 1 December 1968 when the second section of the line was opened between Highbury & Islington and Warren Street. Disused passages remain with tiling and posters from the 1960s.
The station is near Euston Square station allowing connections at street level to the Circle, Hammersmith and City and Metropolitan lines. Ticket hall improvements will start to take place from August 2015, when the ticket office in this station closes. Work will last for up to 12 weeks as we install additional ticket machines. The ticket office will not reopen when the work is complete. To pay for travel, you can now use your contactless payment card, use the smarter ticket machines to buy tickets and/or top up your Oyster card. You can also do this online or at nearby Oyster Ticket Stops. The station has cash machines, Euro cash machines, toilets, escalators payphones and wi-fi. NOTE: Only the Overground and National Rail are wheelchair accessible.
