Iconis integrated control centre image 1Alstom, as leader of a consortium1, has been awarded a contract by the Sardinian Regional Transport Company (ARST) to supply and install a new signalling system for the Monserrato-Senorbì and Macomer-Nuoro lines in Sardinia. The overall project value is about €33 million, of which Alstom’s share is €25 million. The signalling system will be delivered in 2015.


Both lines combined are 90 km long and include 20 stations. 34 regional trains circulate on the Monseratto –Sernobì line and 16 on the Macomer-Nuoro line. The project involves the implementation of the complete railway signalling system for both lines.

It includes ACC-M railway signalling system2, a computerised multi-station interlocking, and Traffic Management Systems (TMS) at the control centre of each line. It also involves the supply of level crossings, passenger information, video surveillance and anti-intrusion systems.

Based on Alstom’s multi-station Smartlock and Iconis control centre solutions, the new system will allow ARST to manage rail traffic in real-time on both lines in an efficient, fully automated manner. Guaranteeing timely decision-making and rapid reaction times, the system will enable a 100% increase in traffic capacity on the Monserrato-Isili line and a 70% increase on the Macomer-Nuoro line.

Alstom’s Bologna site (600 employees), the group’s railway signalling centre of excellence, will be responsible for designing and producing the systems in collaboration with the Bari railway signalling research and development centre (50 employees).
