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 |
