The key driver for this project was assessing and reducing the risk and consequential impact of a train to train collision following a SPAD. The core functionality of the system can be split into 3 areas and this is carried out for both existing railway and for all infrastructure change projects:
As part of Network Rail’s on-going safety and performance improvement commitments and in compliance with the requirements of RSSB’s Railway Industry Standard Reference RIS-0386-CCS, Network Rail developed a bespoke web based tool to quantify, mitigate and manage risk associated with overrun risk within UK infrastructure. The resultant software package was the Signal Overrun Risk Assessment Tool (SORAT).
SORAT is a truly innovative solution, taking a novel approach to the measurement of this specific operational risk. SORAT sets the worldwide benchmark for managing overrun risk.
Our powerful risk management tool – which was written from scratch and uses a large amount of complex mathematical algorithms – helps Network Rail to improve performance and more importantly the on-going safety across the whole rail network.
To deliver the system, we worked with the Research and Development team within RSSB in order to understand the bespoke nature of the risks and mitigations.
Network Rail have nominated SORAT for the national partnership awards and updated releases of the system are already planned which will build in other risk assessment methodology such as SPAD into Level Crossing and an assessment of risk for trackside workers.
Technical Specification
SORAT is a fully web based tool which is hosted within Network Rail environment but is available to users both internal and external to Network Rail. SORAT is designed using enterprise level architecture using Java J2EE and Oracle 11g as the relational database management system. The solution has been deployed on WebSphere Application Server v7.0.
Go Live and System Support
SORAT has been live for 3 years and has been received exceptionally well by the industry. There are currently 300 risk assessors with access to the system and over 13000 risk assessments have been completed since go live.
SORAT is ready to be implemented elsewhere and may be available within 6 weeks of sign up. The solution on offer will be hosted and supported by RSK Business Solutions Ltd or we can configure the system to work within the client’s network.
The system can be calibrated to fit with any infrastructure environment with possible guidance from RSSB research.
System training is carried out by RSK Business Solutions Ltd or we can offer train the trainer guidance to get trainers up to speed with the system, the process and the algorithms. RSK Business Solutions also offer technical support on the SORAT process and manage the part 2 competence assessments for newly trained assessors.
