To Our Bulk and Industrial Customers,
Today, Union Pacific filed a Complaint with the Surface Transportation Board (STB) challenging BNSF's changes to its reciprocal switching tariff (Switching Book 8005-E), which took effect May 1. With no advance warning or explanation, BNSF made significant changes to rates and services that have been working for decades.
What BNSF did:
BNSF has offered no cost, network, or operations-based justification for these changes. The targeted locations are where customers have recently moved business to Union Pacific or increased their volumes with Union Pacific.
What we are asking the STB to do:
BNSF’s approach is in stark contrast and direct conflict of Union Pacific’s goals to enhance competition, expand access, increase service speed and reliability, and improve the overall customer experience. A level playing field is essential for customers to compete and win.
We welcome competition with BNSF on rates and service. What we cannot accept is a targeted effort to foreclose the competitive options customers have built their supply chains and facilities around. Customers have supported our filing, we referenced a few, but others are concerned about further retaliation. Restoring the pre‑April tariff is the right outcome, for customers, for competition, and for the industry.
Thank you for your partnership. We remain committed to supporting customers as this process moves forward and to preserving the competitive options they rely on. If you have questions or would like to discuss your specific situation, your Union Pacific sales representative is available to help.
Sincerely,

Kenny Rocker
Executive Vice President, Marketing & Sales
