The high-speed railroad from Dallas to Houston has acquired a key new player that will run day-to-day operations.

Renfe, an international railway company based in Spain, has been hired by Texas Central, the project developers, as the train's operating partner.

The selection of Renfe as an operating partner marks another major step forward for the Houston-to-North Texas high-speed railroad.

Texas Central CEO Carlos Aguilar says in a statement that Renfe was chosen after a review of the best railroad operators in the world.

"Renfe has established a reputation for excellence in railroad operation in Spain and across the world, and we welcome them aboard," Aguilar says. "With their decades of expertise, they were a natural fit to join our other partners. Having the operator, the design build, and technology teams all on board and able to collaborate will ensure all aspects of the railroad are integrated and efficient."

A release calls Renfe "one of the world's most significant railways operators," running 5,000 trains daily on 7,500 miles of track. The company is integral to the transport system in its home base of Spain, handling more than 487 million passengers and 19.6 million tons of freight moved in 2017.

Renfe, in partnership with Adif, which manages Spanish railway infrastructure, will be responsible for running the trains; maintaining system components, such as engines, signals, and other equipment; and overseeing ticketing, passenger loyalty programs, and other services.

It will also provide technical advice on the design and construction of the Texas train and assist in the further development of Texas Central's operation and maintenance plans, preparing the railroad for passenger service.

Renfe is one of the biggest companies in Spain, employing nearly 14,000 people and recording revenues of 3.6 billion euros in 2017. Its high-speed systems were used by more than 36 million passengers in 2017. In March, Renfe announced that it had posted a net profit of 70 million euros in 2017, thanks in part to a jump in the number of its high-speed passengers, chalking up five consecutive years of growth.

Renfe president Isaías Táboas says the deal is a boon for Texas and for the Spanish railway industry.

"Texas Central represents a large high-speed train project in a country with high-growth potential, for which the Spanish experience will be of great help," he says. "Both Renfe Operadora and Adif have accumulated years and miles of high-speed railway development with professional teams, extensive experience, and specialized knowledge. We are committed to the success of Texas Central in improving the mobility of Texans and others in the U.S."

The agreement comes about a week after Texas Central engaged multinational firm Salini Impregilo ­— operating in the U.S. market with The Lane Construction Corporation — to lead the civil construction consortium that will build the passenger line, including viaducts, embankments, and drainage.

Spain's first high-speed line between Madrid and Seville was dedicated in 1986 and Renfe's first high-speed service connected the cities in 1992.

Its second high-speed line, from Madrid to Barcelona, was completed in 2007. Renfe also operates high-speed service from Barcelona to Paris, Lyon, and Toulouse in France. Among other major international projects, Renfe operates the recently opened high-speed train between Mecca and Medina, in Saudi Arabia.

The 200 mph train will link Houston and Dallas in 90 minutes, with a midway stop in the Brazos Valley.

The Texas train will be based on the latest generation of Central Japan Railway’s Tokaido Shinkansen train system, the world’s safest mass transportation system. It has operated for more than 54 years with a perfect record of zero passenger fatalities or injuries from operations and an impeccable on-time performance record.

Texas Central and its partners are refining and updating construction planning and sequencing, guided by the Federal Railroad Administration’s recently released draft environmental impact statement. The FRA now is working on a final environmental review that will help determine the project’s timeline and final route.
