Other roadway includes grading, bridges and tunnels, signals, buildings, and other road assets.

[b]

For retirements of depreciable railroad properties that do not occur in the normal course of business, a gain or loss may be recognized if the retirement meets each of the following three conditions: (a) is unusual, (b) is material in amount, and (c) varies significantly from the retirement profile identified through our depreciation studies. In the second quarter of 2024, we sold a large portion of an intermodal equipment asset class resulting in a $46 million gain recognized in other expense in our Condensed Consolidated Statements of Income.
