title: BNSF Accused of Significant Grain Freight Rate Hikes Post-Merger
---

Union Pacific has filed a complaint alleging that BNSF Railway significantly increased its charges for hauling grain, with some rates escalating by as much as 472%. The complaint, lodged with the Surface Transportation Board (STB), contends that these substantial price hikes began after BNSF’s acquisition by Berkshire Hathaway in 2006.

According to Union Pacific's filing, the alleged markups have impacted grain producers and shippers across multiple regions. The complaint details specific instances and percentage increases in freight rates for grain transport, suggesting a pattern of price escalation that has occurred over time. Union Pacific, a competitor in the rail freight market, has brought this issue to the attention of the regulatory body overseeing rail transportation in the United States.

The Surface Transportation Board is expected to review the complaint and the evidence presented by Union Pacific. The outcome of this review could have implications for rate-setting practices within the freight rail industry, particularly concerning agricultural commodities.
