Modern control systems are distributed, complex networks, often requiring the configuration of a variety of subsystems deployed in both wayside and on-board locations. These factors, together with the harsh railway operating environment and the desire to protect from unintended or unauthorised access require significant effort to assure and maintain system integrity.

Additionally deliberate attempts to disrupt the rail system through physical vandalism or virtual cyber attacks are an increasing risk to rail system performance and safety. As the railway moves towards standardised technology such as Commercial Off The Shelf (COTS) products and migrates towards more open data solutions, the threat of these sorts of attacks increases.

To address these issues the Rail Control Systems team offers a full range of services associated with providing assurance of the integrity of railway signalling, communications and control systems. These include Reliability, Availability and Maintainability (RAM) engineering, Electromagnetic Compatibility (EMC) and Electrical System Compatibility (ESC), earthing and bonding and cyber security consultancy services.

Through undertaking these services we work closely with our clients to ensure that their railway assets are designed, built, operated, maintained and managed in a way that meets demands of the increasingly hostile environments in which they need to operate in.

Specific examples of the types of system integrity activities we have previously undertaken include:
  • Project RAM and EMC control plans
  • Defining system availability targets and acceptance criteria
  • Undertaking maintainability audits
  • Providing specialist services such as cyber-security threat assessment

Our team has experience of fulfilling a wide range of client requirements, including the delivery of defined packages of work or fulfilling posts on an interim basis.
