Toei Class E5000
The E5000 is a class of four DC electric locomotives operated by Tokyo Metropolitan Bureau of Transportation in Japan.
Four locomotives were delivered from Kawasaki in 2005 for use in hauling linear-motor powered Ōedo Line trainsets to the Magome Workshops on the Asakusa Line in Ōta, Tokyo for heavy overhaul from 2006, following the completion of the Shiodome Link Line. They are single-ended locomotives which work as permanently coupled pairs.
Manufacturing history
Initially, the Tokyo Metropolitan Bureau of Transportation had planned to build a factory facility at the Kiba Inspection and Repair Yard to carry out major and general inspections of Oedo Line rolling stock. However, due to the high construction costs and the planned renovation of the Asakusa Line's Magome Inspection and Repair Yard, it was decided to build a connecting line called the "Shiodome Link Line" between the Oedo Line and the Asakusa Line, which have the same track gauge and are both electrified by 1500 V DC overhead lines.The Shiodome Link Line starts at Shiodome Station on the Oedo Line, crosses directly above the JR Yokosuka Line's Tokyo Tunnel, directly underneath the Route 2 Loop Road, the Tokaido Shinkansen, and the Tokaido Main Line, and terminates between Daimon and Shimbashi on the Asakusa Line. It was completed and opened for use on April 1, 2006. It has a single-track box-type tunnel structure with a length of. It features an radius curve and a gradient of approximately 48 ‰ along the way.
