Under the contract, the Kiewit subsidiary will define the scope, execution plan, schedule and price for a design-build contract, which is expected to be signed by the end of the year.

Texas Central says adding Mass Electric Construction to its list of contractors is a further example of the railway’s integrated approach. From the beginning of the project, construction on which is expected to start next year, everything - the trains, infrastructure, and supporting high-speed technologies - is designed to work together as an integrated unit, mirroring the approach used on Japanese Shinkansen lines.

Central Japan Railway (JR Central) is a financial backer of the Texas project and the US railway is based on the Tokaido Shinkansen. The 320km/h line will deploy rolling stock based on the railway’s latest mode, the N700s, which is scheduled to enter service in Japan next summer.

Texas Central awarded a design-build contract for the $US 20bn project to Salini Impregilo and its US subsidiary Lane Construction in September.
