Leases [Abstract]
Lease Accounting	Lease Accounting Lessee Arrangements We lease a variety of transportation equipment (primarily railcars), terminals, land and facilities, and office space and equipment. Lease terms vary and can range from short term (not greater than 12 months) to long term (greater than 12 months). A majority of our leases contain options to extend the life of the lease at our sole discretion. We considered these options when determining the lease terms used to derive our right of use assets and associated lease liabilities. Leases with a term of 12 months or fewer are not recorded on our Unaudited Condensed Consolidated Balance Sheets, and we recognize lease expense for these leases on a straight-line basis over the lease term. Our “Right of Use Assets, net” balance includes our unamortized initial direct costs associated with certain of our transportation equipment leases as well as our unamortized prepaid rents, our deferred rents, and our previously classified intangible asset associated with a favorable lease. Current and non-current lease liabilities are recorded within “Accrued liabilities” and “Other long-term liabilities,” respectively, on our Unaudited Condensed Consolidated Balance Sheets. Lessor Arrangements We have certain contracts discussed below in which we act as a lessor. We also, from time to time, sublease certain of our transportation and facilities equipment to third parties. Operating Leases During the three and nine months ended September 30, 2023 and 2022, we acted as a lessor in a revenue contract associated with the M/T American Phoenix, included in our marine transportation segment. Our lease revenues for this arrangement were $6.0 million and $17.7 million for the three and nine months ended September 30, 2023, respectively, and $1.8 million and $10.5 million for the three and nine months ended September 30, 2022, respectively. The M/T American Phoenix is under contract through mid-2027, and for the remainder of 2023, 2024, 2025, 2026, and through the expiration of the contract in 2027, we expect to receive undiscounted cash flows from lease payments of $6.0 million, $25.9 million, $29.6 million, $30.7 million, and $15.2 million, respectively.
