The Class I railroad network in the US is projected to experience a gradual decline over the forecasted period from 2024 to 2028, decreasing from 90.68 to 89.35 thousand lane miles. This decline indicates a consistent reduction in the rail network, with an average annual decrease of around 0.37% over the five-year period. Notably, from 2023 to 2024, there was a slight decrease, setting the trend for the subsequent years.

Future trends to watch for:

Infrastructure investments aimed at modernizing existing rail networks may impact future length and efficiency.
Regulatory and environmental policies could further influence rail network expansions or reductions.
The adaptation of rail services to changing logistics and transportation demands, potentially affecting rail lengths.
