Its origins are in 2 early tube railways – the City & South London Railway (C&SLR) and the Charing Cross, Euston & Hampstead Railway (CCE&HR)
The City & South London Railway opened in 1890 and was the first electric tube railway in the world. It’s circular, iron lined tunnels were shield driven through the London clay at a deep level. When the line was opened it operated a 5 minute service, and the windowless carriages with upholstery reaching almost to roof level, became known as ‘padded cells’. In its first 11 days it carried 165,000 passengers.
King William Street
The line was short, 3.5 miles, with stations at King William Street, Borough, Elephant & Castle, Kennington, Oval and Stockwell
An extension of the line, from Borough to Moorgate and then Angel, Islington, was opened in 1900, and in 1907 the line was extended north to Euston.
Charing Cross, Euston, and Hampstead Railway
Opened in 1907, from Charing Cross to Golders Green, with a branch from Camden Town to Highgate
It was opened by David Lloyd George, and was c.8 miles long, comprising 16 stations, which were designed by Leslie Green

Extension from Clapham to Morden started in 1923
During the construction, as many as 18 shields were in use simultaneously. The line was opened in 1926, the same year as the Charing Cross to Kennington link
The stations on this new extension were built in a style conceived by Charles Holden
It was around this time too that the joint Hampstead Line and C&SLR became termed the Edgware, Highgate and Morden Line, and later the Morden-Edgware Line. In 1937, it became known as the Northern line.
