Environmental Impact Assessment of Electromagnetic Fields for Major Rail Schemese
In the UK, construction schemes are required to consider their impact on the local environment, taking into account for example noise, pollution, impact on local water courses, vegetation, wildlife and human health.
Electromagnetic Fields (EMFs) are generated wherever electricity is produced, distributed, and consumed including by railway electric traction systems, power lines and electrical and electronic equipment. EMFs may also be generated intentionally by radiocommunication systems. Strong EMFs can have a short-term impact on human health. The effects of EMFs are highly localised and have the most potential to affect people in buildings and locations that are immediately adjacent to high voltage traction power distribution equipment, electricity sub-stations and transformers. EMFs can also affect the correct operation of vulnerable equipment and systems and managing these types of occurrences is the discipline of electromagnetic compatibility (EMC).
The Transpennine Route Upgrade (TRU) is a multi-billion-pound, transformative, long-term railway infrastructure programme that will improve connectivity in the North of the UK. Stretching across the North of England between York and Manchester, via Leeds and Huddersfield, the 76-mile Transpennine railway serves 23 stations, crosses over and dips under 285 bridges and viaducts, passes through six miles of tunnels, and crosses over 29 level crossings. TRU will transform this line into a high-performing, reliable railway for passengers with greater punctuality, more trains and improved journey times. To achieve this, the route will be electrified, potentially causing significant change to the local electromagnetic environment (EME).
An early stage of the TRU project was to assess the environmental impact of the proposed scheme and a crucial part of that assessment was to consider EMFs. Focus was initially on route section W3, Huddersfield to Westtown, as shown in red below. The assessment investigated baseline conditions and characterised the current EME of the study area with respect to EMC and Human Exposure to EMFs. The impact of the Scheme on the EME in the study area was evaluated with mitigation measures identified where necessary.

Prime Contractor Issues Integrating Distributed Systems on Large Naval Platforms dy
Prime contractors have significant EM issues to manage when dealing with integrating distributed systems on large naval platforms of diverse COTS and MOTS EMC standards, integrating systems from different manufactures equipment distributed through multiple ships compartments of differing EM environments / construction. This involves a risk based EMC approach, for the intended EM environment early in the EMC design cycle, supported by functional testing during setting to work, systems acceptance and whole platform acceptance through sea trials. The challenge is to adequately define responsibilities between equipment manufacturer, system integrator and whole platform integrator (prime) for the overall EMC certification of the ship.
Jon Burbage joined BAE Systems in 2007 after a brief stint working in Australia. Jon is currently the Head of Electromagnetic Environmental Engineering across all BAE Systems Naval Ships projects. Previous to this role, Jon was Group Leader for the Electromagnetic Modelling Group in the Advanced Technology Centre in Bristol. Jon has worked extensively on the Queen Elizabeth Carrier project for 16 years where he had responsibility for the delivery of both ships in all areas of Electromagnetics (including RADHAZ, Mutual Interference, EMC, EMP, Lightning Protection, ESD) RCS and TEMPEST. He has over 25 years Defence Industry experience in Naval (surface & sub-surface), Airborne & Land.
Jon is a Fellow of the Institution of Engineering and Technology and has been a Chartered Engineer since 2005.
A Chartered Engineer with over 33 years’ worth of experience in design and test for electromagnetic / environmental effects, EM security and general RF engineering. This has been achieved in the both the Civil and Military arenas, covering Land, Sea and Air aspects. Experience covers the whole CADMID life cycle including in-service support to cure operational deficiencies due to faults and ageing, verification and validation, technical assurance, customer training and legislative compliance assessments.
Adrian has been responsible for controlling the Electromagnetic Environmental Effects engineering aspects of platforms and products for major UK platforms and upgrades, based on both UK / US military and civil standards. Effects addressed were HERO, HERP, HERF, HIRF, PEDS/TPEDS, TEMPEST, MEMIC, Antenna Polar Plot, Lightning, ESD, Bonding and general compatibility requirements capture/management, design assurance, qualification and proving activities from conception to midlife update and finally disposal.
A career spanning 50 years, Graduating Edinburgh University in 1973, then Work for EMI Electronics (becoming part of Racal & Thales) on Radar and Electronic Warfare Design, and on EM related disciplines in the UK and in the US, then from 2003 to 2017 worked through BAE Systems on the Future Aircraft Carrier, Queen Elizabeth Class, Leading the EME aspects (including RADHAZ, Mutual Interference, EMC, EMP, Lightning Protection, ESD, and RCS) from 2003-2008, then as a EEE Consultant from 2008 to 2017. Finally, from 2018-present carrying out a number of EEE related studies for BAE systems, including in 2022, the effects and risks of EMF in Implanted Medical Devices.

EMC Process for Authorization, a Railways Perspective
Large railway infrastructure projects are characterised by a wide range of specialist and commercial off-the-shelf electrical/electronic including traction power, high & low voltage power supplies, signalling & telecommunications, IT and electro-mechanical equipment.
Railways systems must operate reliably and safely. However, much of the equipment described above operates at different power levels and over frequency ranges from DC to several GHz. Often, this results in a very complex electromagnetic environment and challenging EMC requirements.
This paper explores the development of the regulatory framework for EMC applicable to the European Railways (including the UK), and their constituent subsystems. Reference is made to some recent EMC project assurance works delivered by Mott MacDonald, which successfully applied the outlined requirements and processes.
Maya is working as a technical principal, EMC and is the Lead EMC Engineer for HS2 Area North - civil buildings and assets, for which Mott MacDonald is the designer. Previously, Maya was the Interoperability Manager for Crossrail. She led the development of the Project Authorisation Strategy for the Central Operating Section of Crossrail and secured the timely authorisation of the complete route for passenger service by the Office of Rail and Road. Maya has been the convenor of the CENELEC working group on EMC between rolling stock and signalling for more than 10 years, responsible for the production of four European Norms. Maya is also a registered expert with the Innovation and Networks Executive Agency to the European Commission and involved in the technical evaluation of ERTMS and Interoperability projects on a regular basis. Maya has an established reputation for delivering working solutions to systemwide integration issues in the past as the Head of EMC and subsequently Head of System Compatibility at Network Rail. She continues to be the chairman of the EMC Support group to the Vehicle/Train CCS Interface Committee at the Railway Standards and Safety Board and leading/supporting several cross-industry initiatives with the Railway Partners organisation.
