Segment Reporting [Abstract]  
Segment Reporting Disclosure Segment InformationThe Registrant's principal wholly-owned subsidiary is BNSF Railway and represents its only operating segment. The financial results are evaluated as one reportable segment due to the integrated nature of the Company's rail network. See Note 1 to the Consolidated Financial Statements of the Company's Annual Report on Form 10-K for information related to the subsidiary's services offered and business operations. As BNSF Railway's operations are not materially different from the Company's, the Chief Executive Officer, who acts as the chief operating decision maker (CODM), assesses the segment at the consolidated level. The CODM uses the Company's consolidated net income to evaluate the overall profitability of the segment and allocate resources across the Company's rail network. Consolidated net income is benchmarked against forecasted targets, historical results, and industry standards and analyzed for trends for organizational strategic planning purposes. BNSF Railway's assets and significant expenses are also reviewed at the consolidated level. See the Consolidated Financial Statements for more information. Additionally, while BNSF Railway operates outside of the U.S., its foreign operations are immaterial to the reportable segment.
