The signal
Alameda Belt Line, a jointly owned short line operator by Union Pacific and BNSF, has been selected to negotiate for a three-year rail contract to provide switching and dispatching services at the Port of Los Angeles and Port of Long Beach. This represents a potential shift in port rail operations, as the contract has been held by Pacific Harbor Line since 1998. The change marks a significant procurement decision affecting approximately 40,000 railcars annually and requires separate negotiations with each port authority.
The selection comes after a competitive RFP process initiated in May 2025, with ABL positioned as an alternative to the incumbent operator. While ABL currently operates no locomotives, it provides critical dispatching services on the Alameda Corridor—the vital infrastructure connecting the twin ports to national rail networks. This transition, pending Board of Harbor Commissioners approval, could reshape how cargo moves between the ports and inland distribution centers, affecting shippers, carriers, and supply chain partners reliant on West Coast port infrastructure.
For supply chain professionals, this procurement shift signals potential operational changes in port rail scheduling, switching fees, and service reliability. The outcome will influence transportation costs and transit times for containerized cargo moving through the region, making this a strategic development for companies dependent on LA-Long Beach port access.
Frequently Asked Questions
What This Means for Your Supply Chain
What if ABL assumes operations and switching times increase during transition?
Simulate a 15-20% increase in average port rail switching and dwell times during a 3-month operational transition period as ABL implements new systems and processes. Model the downstream impact on container velocity, rail network congestion, and freight costs for import/export cargo through LA-Long Beach.
Run this scenarioWhat if ABL's dispatch efficiency reduces rail congestion and improves throughput?
Model the positive scenario where ABL's joint UP-BNSF ownership and dispatch expertise reduce average switching times by 10-15% and increase daily rail throughput. Simulate cost savings and transit time improvements for shippers, and model competitive advantages for intermodal services using LA-Long Beach ports.
Run this scenarioWhat if contract negotiations fail and Pacific Harbor Line continues operating?
Model the scenario where ABL and the ports cannot reach agreement terms, and Pacific Harbor Line contract is extended beyond December 2025. Assess supply chain impact of maintaining status quo operations, including potential rate increases and lack of service improvements.
