The government will contribute €257m to the €385m scheme, with the remainder financed by local authorities along the line. The work will reduce journey times between Paris and Limoges by 22 minutes to 2h 49min.

The government has already committed €1.6bn for track renewal by 2025, €450m for new single-deck EMUs to be supplied by CAF from 2023, €140m to improve reliability and safety, and €5m to install Wi-Fi on existing locomotive-hauled trains.

Average journey times on this line have increased in recent years, partly because operation at 200km/h has been prevented between Paris and Vierzon due to work on the track.
