The RPA, which is a set of regulatory requirements applicable specifically to the project, has taken more than three years to achieve as Texas Central first filed its petition in April 2016.  Texas Central says achieving the RPA is major step forward in obtaining the approvals needed to start work on the project. “It means that we continue to be on track for the two FRA actions - this safety rule and the environmental permit - to both be completed next year with financial close and construction quickly following,” Texas Central says.

“We’re pleased that the FRA recognises the world-class standards set by the Shinkansen and validates our plans to replicate the best safety system in the world, right here in Texas.”

The 390km line will have a maximum speed of 320km/h with an intermediate station in the Brazos Valley.
