Railtrack - Put Back - Category B SPAD Risk
A category B SPAD occurs where a train passes a signal at danger with authority because a stop aspect or indication was not displayed with sufficient time for the Driver to stop safely at the signal due to:
I. failure of signalling or level crossing equipment, or
II. It being returned to danger in error
In this programme we look at some typical examples of where Category B SPAD incidents have occured, We also look at some of the consequences of these incidents that might not be immediately apparent to you.
Understanding the causes and consequences of signal reversions and category B SPADs will assist signallers, signalling technicians, track maintenance staff and other key railway personel to appreciate the actions that can be taken to avoid inadvertantly contributing towards these incidents.
