The forecast for single track railway lines in France indicates a consistent annual reduction from 2024 to 2028. In 2023, the length of these lines stood at approximately 9.98 thousand kilometers. From 2024 to 2028, there is an expected annual decrease in length, with year-on-year declines approximately around 2% to 2.1%. The compound annual growth rate (CAGR) over this period signals an overall downtrend, pointing to a decrease in total kilometers available for single track railways over these five years.

Future trends to watch for include:

Potential infrastructure projects or policies aimed at rail modernization that could influence single track utilization.
Shifts in transportation priorities from rail that may contribute to this downtrend.
Technological advancements that might impact the efficiency and necessity of current track lengths.
