Four locomotives (numbered E5001 to E5004) 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.[1] They are single-ended locomotives which work as permanently coupled pairs.[2]
Manufacturing history
Initially, the Tokyo Metropolitan Bureau of Transportation (TMTB) 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 (12-000 and 12-600 series ). 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 1,435 mm (4 ft 8+1⁄2 in) standard 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 (Tokaido Line, Yamanote Line, and Keihin- Tohoku 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 483 m (1,585 ft). It features an 80-metre (260 ft) radius curve and a gradient of approximately 48 ‰ along the way.
