Identification, recording and investigation of digital anomalies such that those that occur on rolling stock and infrastructure systems can be challenging. Recent examples, such as the investigation by the Rail Accident Investigation Branch (RAIB) of the Cambrian ERTMS signalling incident have highlighted the importance of understanding how complex software-based systems are integrated within the railway network.

To achieve effective risk management, suitable management and technical systems need to be in place, complemented by industry skills and understanding. The requirement for in-depth understanding of potential hazards is increasing as the railway becomes more digital. The overlap between complex software-based system and cybersecurity, particularly maintenance of integrity and availability of digital systems, further adds challenges and complexity.

This webinar will highlight the challenges involved in digital incident investigation, give an overview of current capabilities for asset monitoring and incident identification in use, and outline progress to date on an industry-wide programme to respond to the recommendations of the Cambrian ERTMS report, including increasing digital competency across the UK railway and client-led procurement of complex software-based systems.

Simon French is a graduate of the London School of Economics and joined the railway industry in 1982 as a management trainee. He held a number of operational posts in British Rail and worked on number of major railway projects including the Channel Tunnel and Heathrow Express. In 1998 he joined the client organisation for the Channel Tunnel Rail Link (now known as HS1) as the Head of Operations and Safety. In 2004 Simon joined the newly formed Rail Accident Investigation Branch (RAIB). After six years as Deputy, in 2015 he was appointed to the role of Chief Inspector. The RAIB is the independent body tasked with the investigation of railway accidents in the UK.

Dr Emma Taylor is a Fellow of the Institution of Mechanical Engineers (IMechE) and Past-Chair of the Safety and Reliability Society (SaRS). She has over 25 years of experience across multiple sectors: rail, oil and gas/energy and space, highly regulated environments. As the Head of Digital Safety at rail cyber security solutions firm RazorSecure, she is responsible for setting and implementing strategy to lead integration of safety and cyber security for transport rolling stock: detection, monitoring and asset discovery. She is a Visiting Professor at Cranfield University, mentors widely across sectors and generations, and has received a number of awards, including the 2018 Telegraph Top 50 Women Engineers and Computer Weekly’s Top 50 Most Influential Women in UK Tech.
