 where a train driver is incorrectly given a bell code or green flag telling him to start the train despite the platform starting signal being at danger, and he moves the train past the signal without checking it. This constitutes a signal passed at danger
Signal passed at danger
A Signal passed at danger , in British railway terminology, occurs when a train passes a stop signal without authority to do so. It is a term primarily used within the British Railway Industry, although it can be applied worldwide.-Categories of SPAD:...

 trains, the guard uses a Bell/Buzzer Code to communicate with the driver . Once the doors have closed and platform duties are complete, the guard informs the driver by sending the signal for "ready to start", which is two rings (hence "ding-ding"). There was a debate whether guards should only give the "ready to start" or station staff the "right away" signal if the platform starting signal was clear. The British Railways Board

Unfortunately "Ding-ding, and away" events continue to occur despite the rule change and the introduction of equipment such as the driver's reminder appliance

. On trains which work under driver-only operation (DOO) drivers oversee the whole despatch process themselves and so may be distracted by activity on the platform which causes them to close the doors and move away without checking the signal, as in the Newton rail crash. With driver-only operation now more common, the term "Starting against signal, [where the] signal [is] passed at danger" (SASSPAD) is now used.

Prevention

Main stations such as Peterborough where Driver Only Operation is prominent now have additional indicators fitted to their platform starting signals. Usually fibre-optic, they display CD (Close Doors) followed by RA (Right Away) and are operated by the station platform staff. However these indicators do not remove the need for drivers to ensure the main aspect of the starting signal has cleared, as these indicators are not necessarily interlocked with the main aspects, e.g. where a train needs to vacate a platform but the main signal can only show a subsidiary aspect (two diagonal white lights) because the section is occupied by another train unit or locomotive.
