MIGRATING THE NETWORK:

THE CHALLENGES

2


Level 1 version 2.3.0d

Complexity of roll-out in big stations Rolling out ETCS 1 on a conventional network can’t be compared with previous experiences on HS-lines:

2. MIGRATING THE SYSTEM - CHALLENGES

8

Couldn’t build on previous experiences and we had

to take the time to go through a learning process

Complexity grows very fast with number of switches number of unique routes per signal too large

Need for Engineering rules to cope with this challenge, to reduce complexity


Level 1 version 2.3.0d 2. MIGRATING THE SYSTEM - CHALLENGES

9

Lack of version 2.3.0d-compliant rolling stock Different causes:

Impossibility for some RU’s to migrate their rolling stock in time

RU’s often continue buying tailor made OBU’s, not always fully TSI-compliant

IM has to program its trackside system to allow those trains

to circulate, which leads to a suboptimal way of operating

our network, not being able to use the full capacity.



Availability of GPRS in 2.3.0d for ETCS Level 2

Necessary to counter limited capacity of GSM-R


10

Need for a Baseline-independent solution to avoid

operational restrictions for operators and upgrades

for infrastructure managers



11

Need for full TSI-compliant rolling stock Requests from operators to make specifications for the trackside ETCS Level 2 available to them

Risk for the development of national versions of ETCS OBU

With a strong commitment from infrastructure managers to

respect the TSI, operators should be encouraged to install

a fully TSI-compliant version on their rolling stock



Level 1 Limited Supervision (Baseline 3)

Timely availability of products

Operators signal the inability to buy timely Baseline 3 products for their rolling stock


12

Risk that it might jeopardise the roll-out planning

for IM’s and will necessitate dual signalling

Risk for ETCS 2.3.0d train in STM TBL1+ not able to run on ETCS LS baseline 3 line

Risk for lines to be equipped ETCS LS No trains running on them


13

Conclusions


14

Interoperability Possible Interoperability issues are well known, but need full attention of every stakeholder

Installing ETCS on the conventional network is quite challenging due to

complexity of stations

Multiple transitions STM – ETCS vice versa

Keeping operational rules in line with rules for lineside signalling

Conclusions


15

Today 19% of the Network is equipped

By 2022 the whole network must be ETCS!

Our planning is ambitious.

A conventional network is continuously evolving i.e. new track-layout, reduce of number of switches, … in parallel with the Roll-out of ETCS we already need to implement changes on ETCS-equipped lines!

Migration Migration towards ETCS and the operation of an ETCS-equipped network is extremely challenging for an organisation – need for cultural and organisational change.
