when was the subway in new york built
New York City Subway By the time the first subway opened in 1904, the lines had been consolidated into two privately owned systems, the Brooklyn Rapid Transit Company (BRT, later Brooklyn–Manhattan Transit Corporation, BMT) and the Interborough Rapid Transit Company (IRT). The city built most of the lines and leased them to the companies.[45] The first line of the city-owned and operated Independent Subway System (IND) opened in 1932;[46] this system was intended to compete with the private systems and allow some of the elevated railways to be torn down, but stayed within the core of the City due to its small startup capital.[11] This required it to be run 'at cost', necessitating fares up to double the five-cent fare popular at the time.[47]
London Underground The Underground has its origins in the Metropolitan Railway, the world's first underground railway. Opened in 1863, it is now part of the Circle, Hammersmith & City and Metropolitan lines; the first line to operate underground electric traction trains, the City & South London Railway in 1890, is now part of the Northern line.[7] The network has expanded to 11 lines, and in 2016â€“17 carried 1.379 billion passengers,[3] making it the world's 11th busiest metro system. The 11 lines collectively handle approximately 4.8 million passengers a day.[2]
