1 Signalling Equivalent Unit UIC Workshop Chris Binns Senior Programme Engineering Manager 17 th December 2008

2 Background to SEU Modelling in Network Rail In October 2002 at the beginning of Network Rail operation signalling scheme costs were analysed Actual costs for twelve Signalling Renewal projects commissioned between 1996 and early 2003 were reviewed Representing renewal of 6.1% of the whole network so statistically significant Found that the average cost of signalling activities was broadly consistent when averaged over the total number of controlled trackside assets 2

3 SEU Cost Analysis October 2002 Comparison of Unit Cost Data at 1999 Prices 250, ,000 Unit Cost 150, ,000 50,000 Actual Outturn Unit Cost - GE LTS Barnes Manchester Guildford Woking Dartford Signalling Scheme Leeds First Proof House WARM Ph1 North Staffs WARM Ph2-6 Total of 4,006 SEUs analysed First time that a consistent measurement unit was found 3

4 Strategy for Cost Reduction In 2003/04, analysis of SEU costs continued, and Network Rail managers were briefed on the SEU Model In 2004/05 at the beginning of Control Period 3, a revised contract strategy was launched based on in-house design for scheme definition For largest schemes the suppliers bid for zerovalue 5 year framework contracts with planned projects in the geographical area dependent on continued efficiency savings demonstrated under the framework using the SEU model 4

5 SEU Definition The SEU is defined as: each single trackside output function controlled by the interlocking. Includes: Signals Main Subsidiary Banners Shunts Points Each controlled point end Plungers Including any other attributes that require a particular control function within the interlocking Ground Frames Level crossings associated with the interlocking 5

6 What s included in the current SEU rate? (1) Scoping Optioneering Option development Detailed Design Construction Testing Commissioning Recovery of redundant equipment Project Management and supporting activities 6

7 What s included in the current SEU rate? (2) Feasibility costs Outline design costs Network Rail Project Management (GRIP 1-8) Contractor on site costs, management and overheads and profits Contractor design costs Testing and commissioning Civils associated with troughing, signal structures and bases E&P associated with powering the signalling equipment ( include traction bonding on third rail) Telecoms SPTs, concentrators and CSR. For route works the SEU allows for 33% renewed, 33% refurbished and 33% de-lidded and re-lidded Permanent way associated with insulated rail joints Direct possession management costs 7

8 What s not included in the SEU rate? (1) Permanent way, Electrification, Major Civils, Plant Schedule 4,8 and access condition G Customer information systems Safe Cess pathway Station Alterations Additional costs associated complex multiple stage works where layouts are effectively multiple re-signalled as part of the stage works. Capitalised interest 8

9 What s not included in the SEU rate? examples of abnormals (2) E&P Enhanced power supplies involving costs for Cabling / DNOs Civils Gantries higher volumes than in the baseline specification at 03/04 Access Points for maintenance access Safe Cess New Troughing for full route (1/3 SEU New, 1/3 SEU Open, 1/3 SEU Refurbishment in SEU) Platform Works 9

10 What s not included in the SEU rate? examples of abnormals (3) Miscellaneous Land Purchase Security (known high risk areas) Improved site facilities additional over 03/04 Baseline OPEX Transfer of Control Signaller Training - Incremental training costs for additional staff for transfer of control only Incremental cost for duplication at transfer Overheads Project Management Costs related to abnormal activities Possession Costs related to abnormal activities Contingency related to abnormal activities 10

11 Cost: Infrastructure ERTMS SEU Target Cost Savings Cost Savings Labour Material ERTMS 300, k 69k 250, , k 198k 77k 121k 150, k 100,000 50,000 0 Conventional Base SEU 2002 prices ORR efficiency Network change Other items GRIP 1&2 Conventional SEU with additional items Cost savings 2006 ERTMS Target SEU cost 11

12 Common cost savings from ERTMS Associated detail design and data preparation Flasher units for signals Aspect control due to junction speed limit Route clear of other traffic Points correctly set Power supplies Train protection AWS/TPWS Junction indicators Type of signal Element unchanged by ERTMS Element not required with ERTMS Signallers indications Interlocking safe speed elements Interlocking safe route elements Interface to Interlocking Signal Signal support structure Changed but not removed by ERTMS Signal aspect indication Train in section Route set Detail design and data preparation Train detection Power supplies Trackside Functional Modules (TFM) Trackside cables Installation possessions Ground surveys Structure design Positioning/sighting 12

13 Key changes to SEU costs derived from Level 2 ERTMS (Type D no signals) Equipment Savings No TPWS / AWS No signals or cabling Reduction in power Less trackside installation Less complicated design More preassembly & factory testing Additional Equipment + RBC & balises + Train detection + Marker boards 13

14 How SEU cost reduction achieved Total reduction ( 91k) = Equipment ( 32k) + Less additional ERTMS specific cost ( 13k) = 78k Signalling control panel Train detection/indication Train describer Labour ( 49k) + 8k project management + 2k other costs Feasibility Design development ( 3k) Stopping position Signaller controls and indications Interlocking safe route Interlocking safe speed ( 4K equipment) Signal Level Crossing Point machines Power supplies Interlocking interface equipment (TFM) Cables and route Equipment cases Signal incl. auxiliaries and support structure ( 6k) AWS/TPWS ( 5k) Interlocking interface equipment (TFM) ( 9k) Power supplies ( 3k) Cables and route ( 4k) Equipment cases ( 1k) Point installation Testing and Commissioning Signal sighting ( 2k) Braking distance ( 1k) Ground surveys ( 1k) Signal etc. installation ( 16k) Power supply installation ( 4k) Simplified data preparation ( 4k) Standard signalling designs ( 4k) Structure designs ( 1k) Possession management ( 1k) Testing and Commissioning ( 12k) Key Unchanged Changed Eliminated 14

15 Conclusion SEU Model is now embedded in Network Rail s management of Signalling Renewals SEU model is recognised and underwritten by Network Rail s framework signalling suppliers ERTMS is expected to make further substantial savings in SEU rates Control Period 5 (CP5) declared efficiency and volumes rely on commencement of ERTMS deployment in CP4 ( ) 15
