Questions to the Mayor of London – answered on 9th February 2022.

Broken down by year and line, please provide the number of signals passed at danger (SPAD) incidents on the TfL network since May 2016.
Sadiq Khan
Mayor of London
Transport for London (TfL) is focused on reducing the number of signals passed at danger incidents (SPADs) across the whole TfL network, including London Underground, London Overground, TfL Rail and DLR. On the London Underground network, which has seen year on year improvements in the number of SPADs, there are control systems in place to stop any train that passes a red signal.
Most lines are now automated (the Central, Jubilee, Northern, and Victoria lines) or in the process of being automated (the Circle, Hammersmith & City, District and Metropolitan lines via the Four Lines Modernisation Programme) and this will continue to reduce the number of SPADs across the network. There are still times when automated trains are driven manually, including when the train is moving into the stabling at depots. The DLR is fully automated.
