Amtrak Gains Union Pacific Track Access for Sunset Limited Route in Louisiana

Union Pacific Railroad has granted Amtrak access to a 5-mile stretch of track near Avondale, Louisiana, enabling the passenger operator to reroute Sunset Limited services from 1 April 2026. The agreement resolves a dispute that began in July 2025 when Amtrak threatened Surface Transportation Board intervention over substandard on-time performance.

The track access arrangement addresses operational bottlenecks that have plagued the tri-weekly Sunset Limited service between New Orleans and Los Angeles. Host railroad disputes over track usage rights and priority have become increasingly common as freight operators manage capacity constraints while accommodating mandated passenger services. This Louisiana agreement provides a template for resolving similar conflicts without federal intervention.

Amtrak initiated STB proceedings in July 2025 citing persistent delays affecting the Sunset Limited's schedule reliability. The route covers 1,995 miles across 5 states, making it Amtrak's longest-distance service and particularly vulnerable to freight interference. Union Pacific operates the contested section as part of its Gulf Coast network serving petrochemical facilities and container terminals.

The Avondale area hosts Union Pacific's intermodal terminal and connects to the Huey P. Long Bridge, creating operational complexity for both freight and passenger movements. Financial terms of the track access agreement remain undisclosed, though similar arrangements typically involve per-train fees and infrastructure maintenance contributions.

This resolution follows broader tensions between Amtrak and Class I railroads over performance standards mandated under federal law. The STB has increased enforcement of on-time performance requirements, with passenger operators gaining stronger leverage in negotiations. Recent cases involving BNSF Railway and CSX Transportation have established precedents for forced access agreements when voluntary solutions fail.
