Why does it not pose any danger when a Train Captain drives the train past a
red signal?
While the driving of a train is normally carried out by
ATO ("Automatic Train Operation"), a Train Captain may assume
the driving duty with the train set at the manual mode under certain circumstances.
However, under manual driving, the train movement is still safeguarded by ATP ("Automatic Train Protection"). Even in case
that the Train Captain fails to observe a red signal, the train will be caused to
a stop by ATP within the safety buffer
zone beyond the signal and hence ensure safety.
