Red Aspect Approaches to Signals (RAATS) Toolkit
03/02/2021
The Red Aspect Approaches to Signals (RAATS) toolkit is designed to estimate the number of times a signal is approached at red. It provides a breakdown of the different types of approaches and considers factors such as the train type, the time of day and day of week. The toolkit provides information and graphs and allows these to be exported to Excel.
A signal passed at danger (SPAD) is when a train passes a signal displaying a red aspect without authorisation. SPADs incur delay and cost and can cause serious incidents such as train collisions and derailments.
