1 The application of ERTMS/ETCS Baseline 3 on L2 (Corridor D Milano - Treviglio section) and L1 (Sicily) pilot lines 7/11/2012, Control Command and Railway Communication Conference Lille Gabriele Ridolfi 7/11/ Lille 1

2 Topics: Overview on ETCS Baseline 3 Pilot lines on RFI conventional lines equipped by SCMT class B system Feedback coming out form the preliminary functional analysis 7/11/ Lille 2

3 Why ETCS Baseline 3? More flexibility (and performance) thanks to an extended set of train categories (mixed traffic) Opportunity (and challenges) offered by the new Baseline 3 braking model Use of new function Permitted Braking Distance (packet 52) to manage ETCS L1 application on RFI trackside signalling system Adoption of CR818 for Balise Groups inconsistency management in Level NTC, when Balise Group contains only national data (packet 44) Optimized Radio Infill functionality (CR 742) More effective management of non protected LX (packet 88) 7/11/ Lille 3

4 Why two Pilot lines? The "Level 2" solution is generally the best choice for the Italian Corridors; "Level 1" with Radio Infill represents a specific solution for large shunting areas or installations with old generation interlocking (IXL) then... Milano-Treviglio (section of corridor D) L2 Pilot Line aims to achieve the consolidation of the Requirements Specification for ETCS L2 application on RFI conventional line Sciara-Cammarata (Sicily) L1 + Radio Infill Pilot Line aims to achieve the consolidation of the Requirements Specification for ETCS L1 + Radio Infill application on RFI conventional line 7/11/ Lille 4

Spec (SRS) Trackside design Also intermidiate version of SRS can be used as technical reference for Corridor Call for Tender Trackside equipment Lab tests (simulator) Field tests Functional and Safety Asses.

7 How to garantee SCMT operational service during field test? SCMT uses Eurobalises Radio Infill ETCS SCMT add ETCS packets inside Balise Groups together with SCMT packet 44 after validation of the application process and of the configuration tools L1 Telegram Packet 44 (SCMT Data) Euro Balise 7/11/ Lille 7

11 Feedback from the preliminary functional analysis Comparison between SCMT and ETCS Baseline 3 braking model m m PMF = 135% FLAT TRACK Km/h Km/h k = 0.9, train lenght = 650m k = 0.8, train lenght = 400m 7/11/ Lille 11

12 Feedback from the preliminary functional analysis Constant distance between signals vs variable speed in ETCS L1 Signalling and End of Autority (EoA) Pk 52 LX protection Pk 52 7/11/ Lille 12

13 Feedback from the preliminary functional analysis Constant distance between signals vs variable speed in ETCS L1 Temporary Speed Restriction (TSR) - possible solutions alternative to the systematic use of packet 52 Adding a dedicated Balise Group sending packet 52 N m m. 200 m. PK52 N-1 N-2 TSR Using TSR key to trigger packet 52 D 200 m m. A-A S-A S-B L-1 N-1 N-2 TSR A-D 7/11/ Lille 13

14 Feedback from the preliminary functional analysis Points still open Sudden Temporary Speed Restriction on L1? Mixed (SCMT and ETCS) Balise Groups inconsistency reaction in Level NTC (transition phase) using Balise Groups made of 2 balises Release speed calculation in case of short OverLap ( and preventing onboard OverLap time-out to expire after IXL time- out) Inconsistency between lateral signals and cab signalling due to a failure? Beyond Pilot Line crossing geographical border: armonization of different National values, train data, operational rules 7/11/ Lille 14
