Segment Reporting [Abstract]  
Segment Reporting and Significant Expenses Segment Reporting and Significant Expenses
The Company has two operating segments: rail and trucking. Although the Company provides a breakdown of revenue by line of business, the overall financial and operational performance of the railroad is analyzed as one operating segment due to the integrated nature of the rail network. The Rail column in the table below includes the activities of all CSX entities other than the trucking company, Quality Carriers, and also includes the Company's equity in the net income of equity method investments. As the trucking segment is not material for separate disclosure as a reportable segment, the results of these operations are included as a reconciliation to the Company's consolidated results in the tables below.

The Company's chief operating decision maker ("CODM") is its CEO. The CODM reviews information presented on a consolidated basis, accompanied by supplemental information about the trucking segment separately, for purposes of allocating resources and evaluating financial performance. The Company has determined that operating income is the key measure of segment profit or loss as this measure is the focus of the CODM in developing financial plans, including resource allocation, and evaluating actual financial performance against plan. The CODM regularly reviews operating results broken out by significant expense.
