The question is, why was there a SPAD, (signal passed at danger) when there should have been yellow warning, and double yellow warnings before hand. The train also as AWS (automatic warning system - a warning the driver has passed signals at caution)) and ATP (automatic train protection - slams on the brakes if it passes a signal at danger)
As I said there is much more to this to come out.
EDIT AWS also warns driver of excess speed, at a temporary or permanent track limit.
