The high-speed train between Houston and Dallas still needs an official sign-off before it happens, but a builder has been hired for when that day comes.

Texas Central, the developers of the train, have signed a $16 billion contract with Webuild, an engineering contractor company based in Milan.

Previously known as Salini Impregilo, Webuild is one of the largest civil engineering contractors in the world. They'll be working with The Lane Construction Corporation, a global leader in engineering and construction, to lead the civil construction team that will build the Texas rail line.

According to a release, Webuild is active in more than 50 countries on five continents, including Australia, Europe, Asia, and the Americas.

The company has built high-speed train projects in Europe, along with more complex transportation projects such as the expansion of the Panama Canal, the Grand Paris Express, and the Anacostia River and Northeast Boundary tunnels in Washington, DC.

They've worked in the U.S. since the 1980s but were able to expand their presence in 2016 by merging with The Lane Construction Corporation, based in Cheshire, Connecticut.

Webuild Group CEO Pietro Salini calls the commission an honor.

"Being part of such a challenging project as leader of the design and construction of the railway is a unique experience that we are extremely proud of," Salini says. "This is a wonderful opportunity to further focus our presence in the U.S., our biggest single market, together with Lane, the company building first class transport infrastructure for the country for the past 130 years."

According to the contract, Webuild will execute all the heavy construction for the project, designing and building 236 miles of the alignment, nearly half of it on viaduct and much of it elevated to reduce impact on neighbors and landowners.

Webuild will also build all maintenance and industrial buildings, train depots, and facilities.

The system Texas Central Railroad has proposed will replicate the Japanese Tokaido Shinkansen high-speed rail system, operated by the Central Japan Railway Company (JRC) which, in its 55+-year history has transported more than 10 billion passengers with zero operational passenger fatalities or accidents.

The 200-mph train will be a 90-minute ride between Houston and Dallas, with a midway stop in the Brazos Valley.

In May, Texas Central signed a $1.6 billion contract with Kiewit Infrastructure South Co. and affiliate Mass. Electric Construction Co. to install the train's core electrical systems.

The project has had pushback from some Texas politicians and landowners along the route, but the Biden administration is very pro rail, with a $2 trillion infrastructure package that includes modernizing public transit (commuter rail, buses, stations) and improving and expand the nation's passenger and freight rail network. He recently restored funding to a project that would connect San Francisco and Los Angeles.
