In 2023, the non-electrified railway lines in France measured 10.50 thousand kilometers. The forecast for 2024 indicates a decrease to 10.27 thousand kilometers, marking a year-on-year reduction of 2.2%. By 2025, this is projected to further decline to 10.04 thousand kilometers, at a rate of 2.2%. Subsequent reductions show a consistent downward trend, with a decline of around 2.3% annually from 2026 to 2028. The compound annual growth rate (CAGR) over this period suggests an average annual decrease of approximately 2.2%.

Future trends to watch include:

Increased focus on railway electrification in line with sustainability goals.
Potential policy changes and investments affecting non-electrified railway infrastructure.
Advancements in alternative power sources for rail networks that may alter current projections.
