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...

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...
