The platform headwall corner signals are "true" starters. A Vic line
train running in usual ATO mode will not normally pass a red signal (white

I was referring to the white aspect in my earlier post, not the red one. I
was wondering why some drivers chose to hold at a station, even if they have
a white aspect.

Because they're driving in manual?
