Train Dispatch and Preventing Start Against Signal SPADs
03/03/2020
A Start Against Signal SPAD occurs when a train proceeds from a stand towards a signal and passes it at danger. This type of SPAD can occur if when at a station the driver is inadvertently given an indication by station staff, or the guard, that platform duties are complete. If the driver does not check the signal before proceeding, a SPAD will result.
