Introduction to ERTMS
“We are going to have to make far better use of the existing railway infrastructure.
We have to run more trains on the existing track” – NR chief executive Mark Carne

Key Test Case Scenarios
Train dispatch operation
• Start of Mission within VPCAD
• Start of Mission within IPCAD
• Start of Mission using virtual route
Train located within VPCAD Train located within IPCAD
Route Set?
Driver initiates SoM
Train within
VPCAD or IPCAD?
YES
Train has valid
position
Train issued with FS MA when within
VPCAD.
Train issued with OS MA when within
IPCAD.
YES
RBC transmits indication to
Control Centre that Driver has
initiated SoM and route is not
set, outside IPCAD or train has
no valid position.
YES
Train departs with
OS MA or FS MA
NO
NO

Short block operation
• Based on track sections occupancy
• Train operating in Full Supervision
• First ETCS block section unoccupied
• Not constrained by signal sighting or
braking distance

Inter-vendor RBC Hand-over
• Seamless handover of train between
different supplier’s RBCs
• Siemens ↔ Ansaldo
• Siemens ↔ Infrasig
• Seen by NR as high risk area –
good risk mitigation
Emergency operations
• Cooperative shortening MA
• Unconditional emergency stop
• Emergency stop areas (ESA)

Siemens provide trackside and trains
• Core Section - 24 tph
• ETCS Level 2 + ATO
• Shorter block sections – marker boards

2015-09-14
Great Western Mainline
Alstom and Siemens provide trackside based on existing interlocking areas
• ETCS Level 2 Overlay solution initially
• GWML part of Trans European Network
• Existing ATP equipment obsolete by 2020
• GSM-R as DAS / ATO bearer for further increased capacity

ENIF - A Collaborative Environment
Rail Exec Awards 2014
“Most Interesting Award in Support Equipment”
awarded to ENIF
Cooperation
• Cross-industry initiative
• Stakeholders engagement
• Suppliers active collaboration
Successes
• Common balise layout
• Interoperability
• RBC-RBC Handover

2015-09-14
Key Lessons Learnt
• Integration testing
• key for de-risking overall project deployment
• Stakeholders engagement
• Initial exposure to ETCS in a live environment
• Participation in requirements design and solutions
• Suppliers collaboration to facilitate integration
• IPR concerns not founded
“ETCS will have a huge impact on the railway and it’s vital we thoroughly test our
equipment to get it right first time“– NR Industry Lead Operations Simon Whitehorn
