railway from Farringdon to King's Cross in 1852. Although the plan was supported by the City of London, the railway companies were not interested and the company struggled to proceed. In 1854 the Metropolitan Railway (also known as the Met) was granted permission to build an underground line at an estimated cost of £1 million. With the Crimean War under way, the Met found it hard to raise the capital, and construction did not start until March 1860. The railway was mostly built using the "cut-and-cover" method from Paddington to King's Cross; east of King's Cross it was built by tunnelling and then followed the culverted River Fleet in an open cutting to the new meat market at Smithfield. The railway opened to the public on 10 January 1863, using steam locomotives hauling wooden carriages. It was hailed as a success, carrying 38,000 passengers on the opening day, borrowing trains from other railways to supplement the service. In the first twelve months 9.5 million passengers were carried and in the second twelve months this increased to 12 million. The Met's early success prompted a flurry of applications to parliament in 1863 for new railways in London, many competing for similar routes. The House of Lords established a select committee that recommended an "inner circuit of railway that should abut, if not actually join, nearly all of the principal railway termini in the Metropolis". Proposals to extend the Met were accepted, and the committee agreed a proposal that a new company, the Metropolitan District Railway (commonly known as the District Railway), be formed to complete the circuit. Initially, the District and the Met were closely associated and it was intended that they would merge. The Met's chairman and three other directors were on the board of the District, John Fowler was the engineer of both companies. The construction works for the extensions were let as a single contract and the Met initially operated all the services. Struggling under the burden of high construction costs, the District's level of debt meant that merger was no longer attractive to the Met and its directors resigned from the District's board. To improve its finances, the District terminated the operating agreement and began operating its own trains. Conflict between the Met and the District and the expense of construction delayed further progress on the completion of the inner circle. In 1879, the Met now wishing
