Amtrak’s return to the Gulf Coast will come in 2023, but few details are being disclosed about last month’s settlement in a case before a federal agency that could have national implications over how passenger rail is conducted along freight lines.

An Amtrak official disclosed Friday that a pending settlement ending a legal proceeding before the U.S. Surface Transportation Board will enable a 2023 start of Amtrak service connecting New Orleans to Mobile with four stops along the Mississippi Gulf Coast.
