I don't claim to be an expert on this but if you look at the new tracks Sydney
end of turrella station, there are a set of point which could possibly be used
for shuttle services. I doubt there would be any need to build extra platforms (i
don't know if there is or not) just an adjustment of the time table should do it.

In response to yr question about passenger levels on E/Hills services, my
rostered trains are are packed in the peak hour and well patronated in the off
peak.
