The only deep tube line opened before 1900 was the City and South London RailwayYou are forgetting the Drain, which opened in 1898. It also used centred third rail at first. I got my dates mixed up a bit too. The first four rail electrification of the Met was in 1905, while the Bakerloo opened the next year in 1906, not the other way around. But I'm rather sure Yerkes also thought about his new tube lines when he chose a four rail system. IIRC, the Great Northern originally used a four rail system with both of the conductive rails on the outside. A similar system was tested on the District around High St. Kensington. |
