Investment in Conrail Through a limited liability company, we and CSX jointly own Conrail, whose primary subsidiary is CRC. We have a 58% economic and 50% voting interest in the jointly-owned entity, and CSX has the remainder of the economic and voting interests. We are amortizing the excess of the purchase price over Conrail’s net equity using the principles of purchase accounting, based primarily on the estimated useful lives of Conrail’s depreciable property and equipment, including the related deferred tax effect of the differences in book and tax accounting bases for such assets, as all of the purchase price at acquisition was allocable to Conrail’s tangible assets and liabilities. At December 31, 2023, our investment in Conrail exceeds our share of Conrail’s underlying net equity by $480 million. CRC owns and operates certain properties (the Shared Assets Areas) for the joint and exclusive benefit of NSR and CSX Transportation, Inc. (CSXT). The costs of operating the Shared Assets Areas are borne by NSR and CSXT based on usage. In addition, NSR and CSXT pay CRC a fee for access to the Shared Assets Areas. “Purchased services and rents” and “Fuel” include expenses payable to CRC for operation of the Shared Assets Areas totaling $164 million in 2023, $156 million in 2022, and $147 million in 2021. Future payments for access fees due to CRC under the Shared Assets Areas agreements are as follows: $44 million in each of 2024 through 2028 and $17 million thereafter. We provide certain general and administrative support functions to Conrail, the fees for which are billed in accordance with several service-provider arrangements and approximate $6 million annually. “Accounts payable” includes $198 million at December 31, 2023, and $173 million at December 31, 2022, due to Conrail for the operation of the Shared Assets Areas. “Other liabilities” includes $534 million at December 31, 2023 and 2022, respectively, for long-term advances from Conrail, maturing in 2050 that bear interest at an average rate of 1.31%. Our equity in Conrail’s earnings, net of amortization, was $70 million for 2023, $58 million for 2022, and $56 million for 2021. These amounts partially offset the costs of operating the Shared Assets Areas and are included in “Purchased services and rents.” Equity in Conrail’s earnings is included in the “Other – net” line item within operating activities in the Consolidated Statements of Cash Flows. Investment in TTX We and six other North American railroads collectively own TTX, a railcar pooling company that provides its owner-railroads with standardized fleets of intermodal, automotive, and general use railcars at stated rates. We have a 19.78% ownership interest in TTX. Expenses incurred for use of TTX equipment are included in “Purchased services and rents.” This amounted to $274 million, $256 million, and $246 million, respectively, for the years ended December 31, 2023, 2022 and 2021. Our equity in TTX’s earnings partially offsets these costs and totaled $47 million for 2023 and $53 million for both 2022 and 2021. Equity in TTX’s earnings is included in the “Other – net” line item within operating activities in the Consolidated Statements of Cash Flows.
