High Output Electrification of Western
Presented By Anne Watters
Project Overview
191 route miles of which 12 miles are electrified
London to Bristol - completed by 2016
Bristol to Cardiff - completed by 2017
Project Overview
Where is being electrified
• Crossrail is responsible for Stockley Junction to Maidenhead.
• Electric trains team is completing Maidenhead to Cardiff.
- Initial test site of 20 miles of electrification - September 2015
- First phase is Maidenhead to Bristol - complete and ready for December
2016
- Second Phase is Bristol to Cardiff - to be complete and ready for
December 2017
Quantities to Be installed
Routes 1-9 (Maidenhead to Cardiff)
• 3 New national Grid Supply points (+1 Crossrail)
• 30 AT distribution sites
• Approximately 1000km of single-track
• 16000 pile foundations
• Circa 14000 OLE Structures
• 150+ structures to gauge clear
• 4 major Tunnels
• 1 UNESCO World Heritage site at Bath
Changes to OLE Installation
Moving From Traditional installation to High Output plant
systems
HOPS – High Output Plant System
• 3 Consists to install foundations, steelwork & wiring
• 6 shifts a week
• Minimal disruption to the operational railway
- ALO – adjacent line open working – Allowing trains to still run on
adjacent lines
- 7 Hour Possessions
- Managing down the schedule 4 costs
HOPS – Performance Criteria
• The Invitation to Tender (ITT) detailed a number of key
requirements of the equipment;
-
Performance based specification.
Work with the adjacent line open to traffic
Construct an average of one tension length of OLE per shift
Transit in traffic at 60mph
Easily maintained and reduced whole life cycle costs

Final Works
• Running Cross-overs / Contenary wire
• Cutting in SI / neutral section
• Installing Jumpers
• Panning
• Final Heights and Staggers records
HOPS – Staffing
92 Staff working on the HOPS consists
• OLEC 1 – 38 people
• OLEC 2 – 16 people
• OLEC 3 – 26 people
• OLEC 4 – 6 people
• OLEC 5 – 6 people
Two Ways to OLEC competence
• New Starters (Expected to be over 65 of 92 Staff)
- Completing the training courses
- Completing the Logbooks In Germany & High Marnham
- Being assessed in High Marnham
• Existing OLE Linesmen with additional Series 1 training
- Recording activities in Log books / endorsed by Line manager
- Additional Training and log book sign of on Series 1
Changes to Design
Introduction of a new OLE Basic Design system
Series 1
• Interoperability
• Use of High speed trains with Multiple Pantographs
• Simplified connections to speed up installation
Importance of OLE Design
Series 1 – Designed by Furrer & Frey
• Mono-anchor Booms
• Single insulator cantilevers / registrations
• Reduced number of components
• Reduced flaking of wires
HOOBs & Logistics
Main Elements
• Materials supply and disposal
• Piles + masts + wiring + material disposal
• Infrastructure facilities
• Operations bases
• Swindon
• Materials handling facilities, workshops
• Haulage + Train Movements
• 24-hour cycle, intensity of activity,
