Nature of Operations [Text Block] | 2. Operations and Segmentation The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment. Although we provide and analyze revenues by commodity group, we treat the financial results of the Railroad as one segment due to the integrated nature of our rail network. Our operating revenues are primarily derived from contracts with customers for the transportation of freight from origin to destination. The following table represents a disaggregation of our freight and other revenues:
|  | Three Months Ended |  |  | Nine Months Ended |

Industrial |  |  | 2,057 |  |  |  | 2,194 |  |  |  | 6,160 |  |  |  | 6,206 |
Premium |  |  | 1,722 |  |  |  | 1,956 |  |  |  | 5,190 |  |  |  | 5,581 |

Other |  |  | 28 |  |  |  | 14 |  |  |  | 67 |  |  |  | 39 |
Total operating revenues |  | $ | 5,941 |  |  | $ | 6,566 |  |  | $ | 17,960 |  |  | $ | 18,695 |
Although our revenues are principally derived from customers domiciled in the U.S., the ultimate points of origination or destination for some products we transport are outside the U.S. Each of our commodity groups includes revenues from shipments to and from Mexico. Included in the above table are revenues from our Mexico business, which amounted to $673 million and $708 million for the three months ended September 30, 2023 and 2022, respectively, and $2.1 billion and $2.0 billion for the nine months ended September 30, 2023 and 2022, respectively.
