2. 2 Electrical Systems Compatibility Key risk area for all new projects
Particularly electric trains
Worldwide issue
Aim is to design trains which are compatible with the infrastructure on which they run
This is the means by which we satisfy our customers
3. 3 What does a rolling stock manufacturer need? A clear set of requirements at the start of design
Design a train which meets the requirements
Demonstrate that the requirements have been met
Gain the necessary approvals
Bring the train into service
4. 4 What has happened in the past? Requirements were unclear at the start of the project
Every project had to determine requirements, sometimes duplicating previous work
EMC= Extra Money for Consultants
The design had to proceed on the basis of worst case assumptions
More requirements appeared when the train was built
Train then had to be shown to meet requirements for which it was not designed
Usually they were met, sometimes modifications were necessary
5. 5 What we need from the infrastructure owners Definition of compatibility requirements for ALL infrastructure
Track circuits
Lineside systems
Electrification
Communications
Neighbouring Railways
Safety Targets
Definition of the railway environment
Electrification configuration
Emissions from infrastructure
Emissions from other trains
6. 6 What Network Rail are mandated to do Group Standard GE/RT8015 Section B6:
establish and maintain information on infrastructure systems, in relation to their susceptibility to EMI
identify and document all safety- critical or safety related systems which could have their safety performance reduced due to EMI.
Document the susceptibility of such systems
Set safety targets
Identify infrastructure emissions
Provide the information on request to train operators and train builders
All data available no later than 6 December 2003
7. 7 What Network Rail have provided Industry Data Initiative (IDI)
Track circuit susceptibility information generally complete
Some information on other systems, but often incomplete
Example: RT/E/C/50014 requirement for ATP:
line current at 100kHz should be less than a specified amount
Limited information on safety targets
Documents are still draft
Not clear that all requirements have been captured (e.g. nothing on regeneration)
Route Asset Register (RAR)
Expected to be a list of all infrastructure
Does not appear to be readily available
8. 8 What Network Rail have yet to provide Remaining susceptibility data
Safety Targets
Emissions from infrastructure
Environment data
Formally released documents
9. 9 Summary Present Status
IDI in present state does not meet GE/RT8015
RAR status unclear
The Way Forward
Both initiatives to be completed and formally issued
Suggest priority given to routes on which new rolling stock is to be introduced
Issue a plan of action to the industry
