Rail service performance tipping points

If railway operators can avoid tipping points, then not only will service performance improve, but it will be easier to identify reliable solutions to poor performance. In partnership with Network Rail we used rail system modelling to identify the conditions that cause performance tipping points for Anglia rail services.   more...

Timetable tuning to improve performance

Small delays, or subthreshold delays as they are called in the rail industry, are the cause of many services arriving late at stations. Previous modelling for the Rail Safety and Standards Board with Greater Anglia showed that on time arrivals can reduce by up to 23% when services suffer from this type of subthreshold delay. This is a relatively large drop in performance, and the challenge for the rail industry is finding the cause of these delays and eliminating them to improve performance.  more...

Rail performance investigation tools

Risk Solutions brought together performance managers from five UK train operating companies to discuss the data and tools they use to investigate train service performance and identify ways to improve passenger journeys.  The aim of this research work, funded by City, University of London, was to identify strengths and weaknesses with the current analytical processes, […]  more...

HS2 running with existing rail services

Risk Solutions are using their SaviRPM rail performance modelling tool with West Coast Partnership Development to explore the potential performance impacts of HS2 on conventional rail, where the services share the same routes.  Modelling various carefully designed timetable options will demonstrate which approach best integrates the new high speed services with existing national and local […]  more...

Does social distancing impact rail performance?

New modelling work and research for RSSB have shown that although social distancing might increase dwell times, the overall performance impact is not significant nor widespread. As train operators welcome passengers back to the railway, the industry needed to understand the impact of increasing numbers and continued social distance to better manage network performance. Good […]  more...

Rail performance modelling

Risk Solutions and City University of London have successfully delivered research for RSSB to explore knock-on train delays, partnering with Greater Anglia, Great Western Railway and Network Rail. The result is Savi, a Rail Performance Model with a set of powerful interactive visualisations of modelling results. Savi is now being used by train operators and Network Rail to explore the most effective ways to improve service performance and build more resilient timetables.  more...

Value for money decision support tool for HS2

HS2 Ltd faces many design decisions in the delivery of high speed rail in the UK. Each design decision has cost implications, and crucially, implications for delivery of benefits. WSP and Risk Solutions have created a whole life value tool for HS2. HS2 and ITS contractors are now using the tool to measure and compare the value of various options, and TO inform design decisions to ensure the benefits of HS2 are realised.  more...

Research award to understand knock-on delay in rail services

Risk Solutions and City University of London have successfully delivered research for RSSB to explore knock-on train delays, partnering with Great Western Railway. The result was creation of a prototype Rail Performance Model and a set of powerful interactive visualisations of modelling results, that can be used to help train operators and Network Rail understand the causes and consequences of reactionary delay.  more...
