November 41890Engineers open a railway deep under London, electric-powered
The cable contractor goes bankrupt, so the line switches to electric power, and a new kind of transport is born by accident.
The City and South London Railway opened between King William Street and Stockwell, running 3.2 miles. It was the first successful deep-level tube railway in the world. It was meant to use cable-hauled trains, but the cable contractor went bankrupt during construction, so it used electric traction instead. That made it the first major railway to do so.
