The ETCS system has also received ISA and NoBo certification.
The new odometry system, which is based on data fusion, can be installed on all train types and in all environments, including harsh weather conditions. Alstom says the data fusion innovation obviates the need for the external radar components currently used to measure location and speed.
Data fusion is the process of aggregating multiple data sources to produce more consistent, accurate, and useful information than that provided by an individual data source. Alstom’s system is built as a hybrid, including both inertial and satellite sensors for the first time, with this equipment installed within the train where it is unaffected by weather conditions. The algorithms can also maintain precise measurements in covered areas such as tunnels.
Alstom will equip 450 trains in Norway with the new standard by 2026, and testing of the first locomotive beginning this month. Infrastructure manager Bane Nor awarded the company contracts worth NKr 1.8bn ($US 184.9m) in June 2018 to equip the country’s entire mainline train fleet of 467 trains of 55 different types with ERTMS and maintain their systems for up to 25 years.
