Industry experience with

ERTMS Level 1 Trackside

A CASAZZA(Ansaldo STS)


First ERTMS/ETCS Level 1 applications

• Experience on ERTMS/ETCS Level 1 applications started in

1999 with ETCSVB Pilot Project (Vienna - Budapest Line)

• Participating companies were: Ansaldo STS, Alstom, Siemens

& Thales


Level 1 lines in commercial operation (1/2)

• Today, there are more than 2700 km of lines in commercial operation

running on ERTMS level 1 in 8 different countries spanning speeds of

up to 300 km/h (Madrid – Lleida – Tarragona)

• By the end of the year, 350 additional km will be added, completing a

total length of over 3000 km worldwide


Level 1 projects in commercial operation (2/2)

• SPAIN– Madrid - Lleida HSL: (460 km) (Ansaldo STS)– Zaragoza - Huesca: (80 km) (Alstom) – La Sagra – Toledo (21 km) (Thals/Invensys/Siemens)– Lleida - Barcelona HSL (190 km) to be commissiones December 2007 (Thals/Invensys/Siemens)– Cordoba-Malaga HSL (155km) to be commissioned in December 2007 (Invensys)

• BULGARIA– Sofia- Burgas: (450 km) (Thales)

• AUSTRIA– Vienna - Nickelsdorf (67 km) in operation tests (Thales/Siemens)

• HUNGARY– Budapest - Kimle (153 km) in trial operation (Thales) – Zalalövö - Hodos (37 km) (Thales)

• LUXEMBOURG– Network (325 km) in operation on several lines (Alstom & Thales)

• GREECE– Athens Central - Airport (30 km) (Alstom)– Athens - Corinth (110 km) (Siemens)

• ROMANIA– Bucharest - Campina (92 km) (Siemens)


ERTMS/ETCS Level 1 features

• ERTMS/ETCS Level 1 can be overlaid on an existing national signalling system

• An industry experience is described in the following two case studies


Case Study: Belgium Test Sites (1/2)

• L96N Test Site (5 km length) on Paris – Brussels High Speed Line & Schaerbeek Test Site (6 km length) on Brussels - Schaerbeek line

• ERTMS/ETCS L1 (applied on an existing line)

• Overlapping on TBL1 + equipped lines

• Timing: June 2003 to December 2005

• 6 LEU complete systems (parallel inputs and serial inputs)

• 50 Balises (fixed and switchable)

• Integration of ETCS L1 packets with TBL 1 + information, using pkt 44

• Product Interoperability:– LEU (Ansaldo STS) – Electronic IXL (Alstom)– ETCS Lineside equipment (Ansaldo STS) / ETCS Onboard subsystem (Alstom)– ETCS Lineside equipment (Ansaldo STS) / KER Onboard subsystems (Alstom)


Case Study: Belgium Test Sites (2/2)

• Temporary upgrade of existing national system TBL1 with ETCS L1 lineside products: TBL1+

• Integration of ETCS L1 information:

• Tests performed succesfully by Infrabel


Case Study: Italy - SCMT NationalSystem (1/4)

• Italian Conventional Lines: national discontinuous systems (SCMT) using ETCS Level 1 components

• SCMT Trackside: Eurobalise® group and LEU (Ansaldo STS )• 3000 LEUs

• 25000 Balises (fixed and switchable)

• 2500 km (equivalent 7000 km of tracks)

• Timing: September 2003 to December 2007

• Product Interoperability:– Lineside equipment (Ansaldo STS, Alstom, Bombardier) /

Onboard subsystem (Ansaldo STS, Alstom)



• SCMT:– Easily upgradeable to ETCS Level 1– Signalling information incorporates ETCS Packet 44:

• Migration to a fully functional ETCS Level 1

– Interoperable Corridor A (Rotterdam-Genoa)

– Lines between main station and High Speed line boundaries (in alternative to Level 2)

• Use of same technological infrastructure:

– Addition of LEU depending from SCMT layout

• Migration mainly through change of telegram data

• Use of radio infill (GSM-R network already existing)



• Integration of ETCS L1 information:

Radio In-fill for ETCS L1 (1/3)

• ERTMS/ETCS L1 performance can be improved by the use of Radio In-fill



• Why Radio In-fill:– it provides information about the next

main signal aspect in advance with respect to the main signal balise group. The on board system can display new information to the driver as soon as it is available, even at standstill, allowing to restart or to release brakes if the next main signal clears

LEU

RadioInfillUnit

– the information is provided via radio therefore in a continuous way, in contrast with the spot transmission of a balise group and the semi-continuous of a loop

– the information is provided in a safe way, the radio transmission being based on the Euroradio protocol



• Enhanced Radio In-fill:– foreseen for ETCS Baseline 3.0– possibility to have two communication sessions simultaneously so to

have seamless infill information related to a chain of main signals


Conclusion

• ERTMS/ETCS Level 1 allows a transparent migration from a national signalling system to an interoperable European standard

• ERTMS/ETCS Level 1 can be supplemented with Radio In-fill functionality so to improve performance (Baseline 2.3.0)

• Performance will be further improved in Baseline 3.0.0 with Enhanced Radio In-fill


Providing competitive railwaysystems for increased rail traffic
