Weather related performance impacts
To understand the weather-related impacts on our network performance, we’ve been collating and analysing data on Schedule 8 delay minutes and associated compensation costs since 2006/07. We have recorded the cost and minute values for weather-related incidents and attributing these under the following nine categories:
The main impacts of weather on the railway are: costs, poor performance (measured by the Public Performance Measure – PPM), and safety risks. Weather impacts vary significantly year-by-year, and this 20 year dataset provides interesting insight into the range and scale of experiences on the railway.
The average cost of all weather-related Schedule 8 payments across our network ranges from £80-100 million per year. If we include missed targets, repairs, and socio-economic costs, this raises this to an estimated £200-300 million per year. Our performance on adverse weather days, measured by the PPM has been 2-4% lower than on normal weather days.
Weather related delay and cancellation data
The charts above are based on detailed incident data. This data provides information about the location of individual weather impacts, the delay minutes associated with unplanned delays and cancellations (known as Schedule 8) and the cost of compensation to train operators for lost revenue.
