The City & South London Railway (C&SLR) was the first deep-level underground "tube" railway in the world, and the first major railway in the world to use electric traction. Originally intended for cable-hauled trains, the collapse of the cable contractor while the railway was under construction forced a change to electric traction before the line opened – an experimental technology at the time.

When opened in 1890, it served six stations and ran for a distance of 5.1 kilometres (3.2 mi) in a pair of tunnels between the City of London and Stockwell, passing under the River Thames. The small size of the carriages with their high-backed seating led to them being nicknamed padded cells. The railway was extended several times north and south; eventually serving 22 stations over a distance of 21.7 km (13.5 mi) from Camden Town in north London to Morden in Surrey.

Although the C&SLR was well used, the company struggled financially. In 1913, the C&SLR became part of the Underground Group of railways and, in the 1920s, it underwent major reconstruction works before its merger with the Group's Charing Cross, Euston & Hampstead Railway, to form what is now the Northern line. In 1933, the C&SLR and the rest of the Underground Group was taken into public ownership. (Full article...)
