Data shows how timetable disruption leads to increased risk of physical harm and signals passed at danger.
On the surface, delays on the railway mean challenging commutes, angry headlines, and general passenger dissatisfaction—but deeper data analysis reveals a more serious correlation.
We can now prove that each additional minute of delay on the network increases the risk of physical harm.
If network delays were eliminated, we would see significant reductions in high-profile, perennial hazard categories. These include staff assaults, slips, trips, and falls, incidents at the platform-train interface, and signals passed at danger (SPADs).
To reach these findings, we combined incident data from our Safe Insights solution with delay data from Network Rail’s TRUST hub. The graphs below reveal the strong correlation between increases in incidents and delay minutes.
For drivers, whether caused by postponed departures, last-minute platform changes, or even major network disruption, delay minutes lead to a clear increase in SPADs.
As disruption and frustration builds, so does the level of aggression toward station staff.
Late trains mean crowded platforms and hurrying passengers, and therefore a higher chance of injury or mishap in the station.
We can’t cut delays at any cost. Sometimes, they’re necessary. During extreme weather, for example, speed restrictions are an essential tool for reducing the risk of derailments. What we can do is make balanced decisions that take all forms of risk into account. Satisfied customers will continue using the railway, the safest and greenest public transport available in Britain today.
