I didn't even know that the area on that side of the highway and train tracks belongs to Altstetten.
Did you look at the details in the press? They are moving the prostitutes to the very industrial area which is on the "Höngg side" of the train tracks, I believe there are 99% industrial buildings, not residential. So if you live in Altstetten as in "Somewhere around Bahnhof Altstetten, Lindenplatz or further up the hill", you are not at all anywhere nearer to prostitutes than before.
Thanks for that info, I seem to have missed it.
Incidentally, I was down the other side of the train tracks a couple of weeks ago and remember there being a decent sized residential block there between the industrial buildings.
Lots of bad smells there already from the recycling plant.
