CASE STUDY
ATM Azienda Trasporti MilanesiMilan Metro Line 1 signalling upgrade
In December 2006, Alstom was awarded a contract by ATM (Azienda TrasportiMilanesi) to renew and upgrade the signaling system of the 29 km Milan Metro Line 1 – which carries 500,000 passengers daily –thereby achieving the highest ridership
on a metro line in Italy.
KEY BENEFITS
Higher performance-The moving block principle of Urbalis 400 provides shorter headways, which leads to a capacity 53% higher. Better commercial speed reduces commute times.
Seamless migration-To avoid disruption of service while existing lines are still in operation, Alstom developed a technique for migrating from a conventional signalling to a radio-based ATC system with minimal line closures.
Optimized Life Cycle Cost (LCC)-The energy saving timing is calculated to transfer energy between accelerating and braking trains. If regenerative braking is unavailable due to long train intervals, the system will make maximum use of train coasting to save energy by up to 30%.
Country……………… Italy
City Context………. A global city with a population of 1.35 million, Milan is the main industrial, commercial and financial center of Italy. Known for its several international events and fairs, Milan hosted the 2015 Universal Exposition.
