NEW: Maersk shifts SoCal import containers to UP from BNSF

“Shifts like this are almost invisible from the outside,” according to a blog post by marketing chief Daniel Devoe of RailState, which extrapolates data from a sweeping network of cameras aimed at rail lines. “Railroads and shippers keep them private, and the volumes don’t surface in quarterly reports until months later, if ever. By reading the ID on every container that passes a sensor, RailState tracked this shift as it happened.”

Maersk currently has contracts with both UP and BNSF (NYSE: BRK-B). The shift also comes as UP extended a $300 peak season surcharge on intermodal traffic moving out of Southern California.

RailState in a recent report found that Union Pacific volume from Southern California to Chicago had been rising in recent weeks.

Approximately 1,000 TEUs of Maersk’s weekly Southern California outbound volume have shifted to Union Pacific, which now handles 77% of Maersk’s volume in that region. These shipments are primarily routed via UP’s Long Beach-to-Chicago service, reaching the Global 4 terminal near Joliet, Illinois, and the Long Beach-to-Dallas corridor, industry observers say.

“A change like this is hard to see from the outside. The volumes may turn up later in a quarterly report, but that can take months, and many shifts are never announced at all,” said Devoe.

Throughout the tracking period, Maersk transported 100,559 TEUs east along this corridor, with 90% previously handled by BNSF. However, after UP maintained only a single-digit share through mid-May, the volume began to shift rapidly. By the week of June 1, UP’s share surpassed 50% for the first time, climbing to approximately 76% by the week of June 8. Since the transition started in late May, UP has accounted for roughly 59% of the total volume.

The shift comes just as the peak shipping season moves into high gear, and UP presses its case for a transcontinental merger with Norfolk Southern (NYSE: NSC). BNSF has been an outspoken critic of the merger.

As an integrated logistics provider, Maersk continuously balances inland capacity across our rail partners to ensure reliable service for customers, particularly heading into peak season,” Maersk said in an email to FreightWaves. “We don’t discuss the commercial terms of our rail relationships, but our priority is delivering consistent transit and capacity for our BCO customers across all U.S. inland corridors. Where routing adjustments affect specific customers, we work directly with them to manage the operational details.”

FreightWaves has also reached out to UP and BNSF for comment.
