Re: Crossing loop design (r.e. Southern Aurora crash)

<<<<<<<<2) Stop required at Home arrival:

Y/R, R/R - the home departure aspect is irrelevant here..

3) Stop required at the Home Departure:
a) via the main...

G/R, Y/R, R/R. - This is a normal speed route because there is no
diversion.

b) via the loop...

Y/G, R/Y, R/R - This is a medium speed route to take the loop.>>>>>>>>>

Yes, you've got it, these aspects would all be fine IF there was sufficient
braking distance between signals.

In the US they get around this by giving you a flashing yellow on the last auto
whenever the departure is red. After the flashing yellow you see the home
arrival which will be either Y/R or R/Y. This system is as good as it gets in
my opinion.
