Bari, 8 March 2026
As part of the technological upgrading and modernisation of the national railway network, the new Multistation Centralised Computer-Based Interlocking System (ACC-M) has been activated at Bari Centrale station, accompanied by changes to the station's rail plan and the entry into service of the doubled line on the last section, over two kilometres long, of the Taranto-Bari line entering the station.
The project, which required a total investment of approximately €120 million, represents a significant step forward in the technological upgrading of the railway network and constitutes a significant turning point for traffic management at the Bari node. The new ACC-M system, which replaces the previous route-based electrical interlocking system (ACEI), acts as the beating heart of the control system, ensuring centralised, secure and highly reliable monitoring of stations and lines, as well as optimal coordination of signals, points and main line equipment.
The result achieved is the fruit of many years of design and implementation, culminating in a final scheduled 72-hour interruption that involved the entire Bari node, with over a hundred people working on site. It was a complex operation, conducted with high standards of safety and quality, which required a high degree of integration between technical, operational and organisational skills.
The activation of the ACC system now makes it possible to speed up some arrival/departure routes on the Foggia side, ensuring greater technological reliability and creating the conditions for the next interconnection of Bari Centrale station with the network to and from Bari Airport. The completion of the doubling of the Bari line increases the capacity of the line and allows for an increase in rail services between the Ionian capital and Bari.
This is an important result, achieved according to schedule, thanks to the close synergy between FS Engineering and RFI which, together with the contractors involved, with over 100 technicians working day and night at the Bari node, all united by the challenging goal of improving the reliability, safety and efficiency of rail traffic, for the benefit of the transport system and the areas served.
