The contract, which was secured with the cooperation of Mitsui, is worth around Yen 20bn ($US 204m) and covers the installation of track and electrification, together with the design and supply of signalling, telecommunications, power supplies, and operation management systems on the 5km section of new line.
MHI will be responsible for overall project management, trackwork, signalling, overhead catenary equipment, and data transmission systems, while Toshiba's share of the contract covers train control, the maintenance management system, power supplies, train radio, and passenger information systems.
Last December Lloyds Register Rail was appointed independent safety assessor for the extension, which is due to open in March 2016.
