Programme

Day one - 25 February 2025

09:00 Registration opens
09:25 Welcome

Roger White, Director, Rail Electrification Consultancy & Richard Williams, Principal Electrical Systems Engineer - Transportation, AtkinsRéalis
  Chair: Richard Williams, Principal Electrical Systems Engineer - Transportation, AtkinsRéalis
09:40 Session 1: Keynote: The part of electric traction no-one notices

Peter Dearman, Independent Consultant, Dearman Engineering & Past PWI President
10:00 Session 2: Protection against electric shock

This presentation covers the importance of protection against electric shock and the dangers of touch voltages. Standards are discussed in detail.

Sarah Dale, Technical Director Traction Power, Mott MacDonald
10:50 Break
11:10 Session 3: Case study one - AT and classic traction return system

This session will answer what we mean by AT Electrification, Classic and Boosterless Classic (Rail Return) schemes and what are the unique and common factors that influence the traction return system designs for each scheme. Good design practices and potential issues will be identified, allowing for principles to be applied to various practical scenarios.

David Atkey, Principal Engineer (E&P Systems), Network Rail
12:10 Session 4: Case study two - Multiconductor modelling to assure the safety and reliability of HS2

Overview of the application of integrated multiconductor simulation to demonstrate E&B and EMC compliance of an electrified railway. It will be shown how models incorporating the traction return circuit and common earth system, longitudinal civils assets, and command and control systems cables can be used to verify the system will comply with touch voltage and induced voltage limits.

Ian Flintoft, Principal Engineer - Electrical Systems Practice, AtkinsRéalis
12:50 Lunch
13:50 Session 5: Case study three - Elizabeth Line earthing and bonding

The Elizabeth Line traction return is configured in the tunnel and station sections. This case study will detail the complexities of earthing and bonding on the Elizabeth Line and how non-traction / civil assets are bonded.

Sarah Dale, Technical Director Traction Power, Mott MacDonald
14:30 Session 6: Earthing and bonding at AC/DC interfaces

Adjacent operation is common where a railway company repurposes an old railway alignment and is often the case with city DC metros being installed parallel to AC railways. The challenge here is that the two systems are operating on adjacent lines and the overhead contact line zone alignment can conflict with the rails, fences and infrastructure of the adjacent railway.

Roger White, Director, Rail Electrification Consultancy
15:20 Break
15:40 Session 7: Earthing and bonding of electrification system assets

Keith Orgill, Director, OLE
16:30 Interactive project sessions

Project 1: Extension of Crossrail Services from Abbeywood to Ebbsfleet: Earthing Bonding of track and conductive assets at AC DC interface.

Project 2: Lightning protection of HS2 conductive assets: on tracks, in stations and on viaduct.

Project 3: East West Rail Link: the options for conductive assets either segregated or integrated bonding.

Roger White, Director, Rail Electrification Consultancy & Richard Williams, Principal Electrical Systems Engineer, AtkinsRéalis
17:30 Close - Informal drinks
