Infrastructure expansion proposed for Rome-Florence high-speed line to address track saturation
Executive summary: The Transport Authority's guarantor, Zaccheo, has requested the expansion of the Direttissima high-speed line by adding two new tracks between Rome and Florence due to current saturation. The current rail corridor is unable to handle the growing volume of trains, impacting service quality and potentially delaying the entry of new rail operators into the market.
Who is involved: Transport Authority (Zaccheo), Italian rail operators, and infrastructure planners.
Likely next: Technical feasibility studies and detailed cost-benefit analyses for the proposed infrastructure expansion.
The Direttissima high-speed line has reached capacity, prompting the Transport Authority to call for the installation of two additional tracks between Rome and Florence. This development follows a period of increasing congestion that began in 2019 and highlights the growing pressure on Italy's primary rail corridors. The project's feasibility remains subject to technical complexities and significant cost evaluations.
What's next — scenarios
Base Case: Infrastructure investment approved (50%)
Long-term capacity increase for high-speed and intercity rail, favoring new market entrants.
- Approval of budget allocations for rail infrastructure
- Technical feasibility reports confirming track integration
Downside: Project stalled by technical/cost hurdles (30%)
Continued congestion and service degradation on the Rome-Florence corridor.
- Cost estimates exceeding government budgetary limits
- Unresolved technical complexities regarding existing track geometry
Upside: Accelerated multi-modal integration (20%)
Faster implementation through public-private partnerships or EU funding.
- Access to specialized EU infrastructure funds
- New private investment models for rail expansion
What to watch
- Publication of technical reports regarding the Direttissima tracks
- Government budget discussions for 2027-2030 infrastructure spending
- Updates from the Transport Authority on rail operator entry timelines
