First post here, one of the arguments I have heard against skyrail is people peering down onto the backyards. However, this would still be better than right now, where, on a train travel home, seen a couple of houses in Hughesdale, where I could see into the house themselves! And besides, there will probably be some screens on either side for privacy.
Yes, added to the fact that any glimpse of a backyard will be a half-second long due to the speed of the train.
Depending on which forum you trawl, there are a variety of myths or half-myths coming from anti-skyrail people. Twitter seems to accommodate some interesting views, as does the No Skyrail Facebook page. People on Twitter just seem to be repetitive, like Mr David "no one voted for skyrail" Davis and others:
#skyrail: no business case, options analysis, EES, comprehensive noise study, No meaningful community consultation #springst— July 19, 2016
They are welcome to their opinions of course, but since construction activities are accelerating, I don't think there's much they can do. At least the Andrews Government, despite some misgivings, is actually doing something and starting projects within a four-year term.
