True, but that could make things difficult since it would mean that if some
trains were delayed, lots of drivers would be off their diagrams, whereas
the current system with 'captive' relay drivers prevents that.

In all honesty I have never heard of any electric train using that emergency
crossover at Edgecliff. 8-) I know track machines and locos on ballast
trains have though.

I'd say that the first pantograph would lose power trying to pull 1500 volts
thorugh the 20 years of accumulated gunk on the section insulator that spans
that crossover...

Also, when you say 'turned around' at Edgecliff or Martin Place, which
direction are you referring to? Do you mean turning trains back towards
Central from these locations, or back towards Bondi? I'm just asking because
the Edgecliff crossover allows for turning back both ways, but Martin Place
doesn't.

Regards,

Craig.
