SPAD stands for Signal Passed At Danger.
If a driver SPADs, they can be suspended by the rail operator. In SimSig, SPADs are not simulated automatically. In reality, the average signaller only experiences a few SPADs in his/her entire working career, so the chances of it happening are very slim. SPADs also have a psychological aspect on both signaller and driver, and as such, are not appropriate in SimSig. Some games may simulate crashes, blood, guts, and gore, but SimSig is not such a game.
In later versions of SimSig, a multiplayer host has the option of causing a SPAD. The reasoning behind this is that it is a controlled SPAD by the simulation host and it is up to him/her to manage the after effects of such an event.
There used to be four types of SPAD:
Nowadays, the former Category A is the only SPAD-type, with B, C and D-types being classed as operational incidents.
See also PSAD (Pass Signal At Danger), a rearrangement of this acronym popular with SimSig players but unauthorised elsewhere. :-)
