The Texas Railroad Commission on Wednesday announced a $1.5 billion bid to build a 1,300-mile rail line connecting the Houston area to Corpus Christi.

The bid, which will be formally presented to the Texas Legislature next month, follows a $700 million proposal last year from the Texas Association of Railroad Commissioners that called for a similar rail project.

The Texas Railroad Commissioner’s Office, which oversees railroads, said the Texas Energy Corridor proposal would add about 3,000 jobs in Texas.

Texas Governor Greg Abbott, a Republican, called the proposal a “historic investment” in Texas, and said it would provide the state with an “effective, reliable and environmentally sound rail line.”

Texas’ oil and gas boom has helped to fuel a boom in rail transit in the United States, with Texas alone adding more than 1,000 rail-transit cars per day between 2014 and 2020.

The proposal comes just days after the Texas Department of Transportation announced a plan to build more than 6,000 miles of new rail between Houston and Dallas.
