Certification Process agreed with ERA 1. Trackside CCS and On Board Unit must be implemented according to the ERTMS Baseline 3 R2 standard and subject to certification. Regarding TRK ETCS, by not exporting application conditions that affect interoperability to the OBU, the certification will be performed by a NOBO 2. The certification of the new on-board and trackside functions that include the introduction of GNSS and the train integrity function will be carried out by a DeBO All the products and functions of GNSS (including the Augmentation Network), which are added to the provisions of point 1, will be used only for the purpose of improving odometry by virtual balise and they are not impeding the line interoperability 8
Working Group to support the certification process ESA ASI GSA ERA ANSF Certification Assessment Process defined of EGNOS underway 9
Challenges Track discrimination – At ETCS SoM (*) The ERSAT-GGC track survey will help in the characterization of the line in terms of suitability of the area for the VB location, i.e. Line green: VB can be placed even at small distances; GNSS Line red: we need different solutions Open Sky Frequent VBs increase performances through odometry reset Reduce SR travelled distance at Start Of Mission RFI is interested in the results of EU projects, as well as technological and market trends (DCMF, Non GNSS Sensors, Data Fusion) to extend current performances also in GNSS VB VB denied zones. 1 2 SR travelled distance 10

RFI «Smart Diagnostic» cofunded by from January 2020 Use Case Application Integrated Systems for “Smart Maintenance”: High reliability, real-time (short latency time), extensive territorial coverage, cybersecurity. The application of 5G technology allows centralizing in real-time a huge amount of diagnostic information that can be collected by sensors, installed wayside along the railway network. Also, measurement systems installed on board RFI diagnostic trains can be centralized in real-time. The integration of satellite technology with the terrestrial 5G network will maximize system performances, ensuring high levels of service coverage and reliability.

Trenitalia contribution and Field Test Results Fabrizio Memmi – Trenitalia 13 November 2019
Trenitalia Fleet, State of the Art High Speed Fleet (ERTMS systems) Rolling Fleet SSB Stock Consistency Supplier Class ETR 1000 50 HITACHI STS ETR500 30 HITACHI STS ETR 500 30 ALSTOM ETR 600 12 ALSTOM ETR 610 7 ALSTOM ETR 485 15 ALSTOM ETR700 17 HITACHI STS Regional Fleet (Class B systems) Nearly 4500 Vehicles (4 SSB suppliers!) 17
ERTMS on Trenitalia Regional Fleet, a long way to go.. First applications of ETCS on regional vehicles for new commercial service on the DD line Roma-Florence E464 Vivalto E40X Semipilota Z1 Vehicle already ERTMS certified, currently in commercial service only on class B lines New Regional Trains will be progressively equipped with ETCS following network installations 18
Improvement of Low-Traffic Regional lines Management: Satellite Technology introduction Use of satellite technology (GPS, GLONASS, EGNOS, GALILEO) in order to obtain: A more reliable and available speed/distance monitoring for train positioning Cost reduction to equip a line with ERTMS system. 19
An opportunity for Railway Undertakings: Integration with Satellite and Virtual Balise 1. Increase in the Availability of the Balise detection chain of Signalling System Now: unreliability of Signalling System due to failures of discrete onboard-inline interface (balises, problems with the on-board antenna…..) Real balise detection With ERSAT: The Virtual balise eliminates malfunctioning related to the detection of the physical balises RUs benefits: Virtual Real balise detection: matching • Savings in energy and time for unnecessary braking between GNSS position and VBR stored position • Savings for time spent at starts of mission 20
An opportunity for the Railway Undertakings (2): Satellite as an additional speed sensor 2. Increase of reliability of Speed Monitoring of Signalling System Now: Problems related to on-board odometry (slipping/sliding wheel), already experienced in ERTMS With ERSAT: Integration of satellite improve the accuracy of the odometry in condition of low adhesion rail/wheel RUs benefits: • Savings in energy and time for unnecessary braking • Savings for time spent at starts of mission 21
An opportunity for the Railway Undertakings (3): Multi-bearer TLC solution 3. Increase of reliability of Communication Network Now: Problems due to weakness of interaction between onboard-trackside totally based on GSM-R standard With ERSAT: Using different bearers (GSM 3G/4G/5G mobile networks, Wi-Fi, Satellite) links may be added or dropped as the train moves in or out of coverage without interrupting the end-to-end connection. 22
Trenitalia needs expected to be solved by ERTMS+SAT program in the long term 1. Reduction of investment and maintenance costs. 2. Modernise signalling system at lower costs to ensure sustainability, according to the European scale numbers. 3. Guarantee a real and long-term interoperable European standard. 4. Improve capacity of transportation networks extending ERTMS system on secondary lines and urban nodes. 5. Minimize Impact on Operational Rules. 23
