I noticed today there were 3 non-yet-active barriers in place along with a gap for what I presume will be a wider spacial access barrier.
So hopefully the gate closure issue will be sorted sooner rather than later.
Still no sign of a ticket machine on the Perry Vale side though.
And one day, when this is all sorted, the underpass might just get a facelift.... so much for the 6 weeks after commencement of building works as Forest Hill Central...
