Alstom will install Italian Railway Network's (RFI) ACC-M multi-station interlocking system together with a traffic management system at the control centre for each line using its Smartlock interlocking and Iconis control centre systems. The contract also includes the supply of level crossing control equipment, passenger information, CCTV, and anti-intrusion devices.
One line links Cagliari Monserrato with Sernobi and is currently operated by16 trains/day/direction. The other line, which only has eight trains/day/direction, is the centre of the island and runs east from Macomer to Nuoro. The new automated signalling system will allow Arst to double the capacity of the Monserrato - Sernobi line and increase capacity on the Macomer – Nuoro line by 70% when the project is completed in 2015.
