AUSTIN, Texas -- A Texas company has secured a $300 million loan to help build a high-speed rail from Dallas to Houston.

Texas Central Partners said the money, which comes from Japan, will let them work on permitting, design and engineering.

They plan to use Japanese bullet train technology. The company said the entire project will cost up to $15 billion and will be privately funded.

The train would take just 90 minutes to get from Dallas to Houston. The proposal still needs environmental clearance.
