Opening of City and South London Railway

Date: November 4, 1890 • Location: City of London, United Kingdom

The City and South London Railway (C&SLR) was the first successful deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotives – an experimental technology at the time – was chosen instead.
