1. ERTMS Level 2 has entered commercial operation in Spain on high-speed rail lines, marking a significant step forward in ERTMS deployment. 2. Testing of ERTMS Level 2 revealed some challenges mainly related to communications problems, but reliability of Level 2 has been better than Level 1 initially. 3. ERTMS Level 1 has been implemented on Madrid commuter lines to increase safety and capacity, and Level 2 testing is underway with the goal of further boosting safety and capacity.

L2 in commercial operation and ETCS in
commuter lines.

8. 2.ETCS L2:Why did we take so
long to put in service?
• First L2 tests on Mad-Lleida line were performed in
June 2006!
•Lack of commitment of some of the involved
partners.
•Priority on developing STM for LZB.
•L1 worked perfectly at 300 km/h.
•Complementary Tests (a kind of reception tests)
were started in June 2009.
• Lines were already in commercial operation and
therefore the testing time was very limited.
8

9. 2.ETCS L2: What are we testing with
L2 Complementary Tests?
• The target of CT are to demonstrate the
correct behaviour of the whole train-track
system.
• CT are a set of 269 tests cases which test
main ERTMS functionality
• Key Management System tests. A KM
procedure has been specifically
developed. (414 KMAC and 85 KTRANS)
• Simultaneous trains tests.
• CTs for S-112 and S-103 trains took 41
test sessions.
9

10. 2.ETCS L2: Reliability Tests
•More than 150.000 kms testing reliability. Main issues arised:
•Communications problems:
•Protocol V110 desynchronization
•HW failures in RBC multiplexors
•Modem train failures.
•Interferences with GSM public operators.
•Track issues:
•Balise linking information (all balises linked in L2)
•RBC functional issues:
•Reception of packet 1 with LRBG value ‘unknown ‘.
•EVC Functional issues:
•Wrong storage of RBC information in SL mode.
•Trains SW updating took almost 3 months.
10

11. 2.ETCS L2: Challenges during L2
putting into Service L2
• Managing of superimposed L1 and L2 TSRs.
• L2 Start of Mission design: TAF procedure
• Transitions Complexity: L0, L1, L2 and LSTM LZB
• Key Management System
• Communication failures: Lack of modems specs.
• CR implementation in 2.2.2+ (SH TR CR 530)
• New operational rules
• Progressive trains upgrading from L1 to L2 (new SW)
in commercial service
• Degraded Odometry
• Command Post operators and drivers training
11

12. 2.ETCS L2: Lessons Learnt
• At the time being one ETCS level is enough!
•Modem lack of specification is a critical issue.
•Different CRs implemented by different suppliers can
lead to IOP issues (in versions 2.2.2+).
•L2 Tests in lab are essential to reduce time and
increase confidence on the system.
•Reliability tests were vital to analyze
communications problems.
12

13. 2.ETCS L2: L2 with L1 as a backup system
Advantages
• Higher availability. A L1 up to 300km/h as backup.
(level inhibition national function needed for transition
process up to put in service L2 in all the lines and trains)
• Levels 1 and 2 superimposed will allow Adif and Renfe
to perform the migration from 2.2.2. to 2.3.0.d
Disadvantages
• Higher cost.
New Spanish HS lines are now
being tendered only with L2 !

14. 3. ERTMS in Madrid Commuter lines
• ERTMS Line C4 (73 km) in L1
• Installed by Thales (South part) and
Dimetronic-Invensys (North part)
•Interface with existing IxL
• Train EVCs are supplied by Alstom
(123 Civia)
• Complementary tests were adapted
to the specific commuter lines
functionality.
•Current headway 4’ in Atocha-
Chamartin tunnel
Safety level has been increased
14

15. 3. ERTMS L1 main issues while
installing and testing
• Geographical information and SSP
updated
• ETCS and IxL timers must be
adapted
• Many and complex Level transitions
• Dynamic 200m TSRs.
• FN 125 needed because of works
still in progress
• Very complex installation
Small size station cables (Nuevos Ministerios C4)
15

16. 3. ERTMS L2 in Madrid Commuter lines
• Installing and testing 2 RBCs
different technologies: Thales
(South part) and Dimetronic
(North part)
• Increase of capacity about RBC
15%
• Up to 60 trains
simultaneously in L2
RBC
Safety and Capacity level will
be increased
