3. RFI migration strategy gives the highest priority to the corridors
Elements of Italian strategy for ETCS implementation Interoperability choices 1
RFI migration strategy gives the highest priority to the corridors
RFI
is carrying out interoperability on the new lines of its High Speed network
Considers as essential a quick realization of interoperability on the lines connecting the Italian HS/HC with the European network (Cross border lines - corridors)
Interoperability will be afterwards realized on other “Amenagées” lines
is going to carry out interoperability also on part of its conventional network
General RFI migration strategy to ERTMS/ETCS

Elements of Italian strategy for ETCS implementation Interoperability choices - applied technical solutions
Extension of SCMT towards ETCS level 1 on Corridors linking Europe
(Consequences for balise configuration, How to solve the infill issue)
ETCS on board without STM Operation conditions
ETCS Level 1 without interoperable infill information
[for areas where only a discontinuous system (BCA - RSDD) exists (V<150Km/h)]
Reduced ETCS functionalities on board
Driver has to drive by line side signals information
Missing on board Info: permitted speed, target distance
Remaining info / functions: current speed, warning for over speed, data entry
ETCS Level 1 with interoperable infill information
[for areas where a continuous system (BACC) exists (V>150Km/h)]
Complete ETCS functionalities on board
Driver has to drive by on board (DMI) information
ETCS Level 2
[for areas where a continuous system (BACC) exists V>150Km/h)]
ETCS level 1, with or without the infill standard information, can be over posed to the existing SCMT system using its Eurobalises (information from packet 44)

Success Key points
Requirement Definition at System and Subsystem level with agreement of RFI and all suppliers (signalling and TLC)
Skilled RFI team in UNISIG Requirements for their configuration
One Example: the right match of parameter for management of the Radio Link connection in GSM-R, RBC and EVC (TNV_contact and his reaction , Safe connection and Euroradio parameter, T_Mute, BitErrorRate and GSM-R work frequency, etc..) in order to achieve the maximum in availability and safety
Strong presence in the field for test results analysis with a deep assessment (independent log analysis by RFI)
ERTMS System Integration in the fields and in independent laboratories with product of different suppliers (with their competition but also reciprocal cooperation)
Developing of predictive diagnostic tools for signalling system
Daily Monitoring by RFI and Suppliers of the results of each run in preoperational period with dedicated retrofit

SCMT Configuration
With BACC (4.500 Km): Encoders with switching balises to send only routes signals aspects and non - switching balises to send line parameters, temporary speed restrictions and reduce odometer error.
Without BACC (6.000 Km):
Encoders with switching balises to send both routes and block signals aspects and non - switching balises to send line parameters, temporary speed restrictions and reduce odometer error.
In the medium term the SCMT balises will have the standard ERTMS message (SCMT will use packet 44 of the standard message)
