Earlier comments in this thread that the Barossa 'locals' wouldn't like the train returning because that would bring additional development in the region only reinforces my argument that development, particularly these days always follows railways. I'm glad that concession was made to my advocacy argument.
Vinelander, you seem not to understand that the close wine producing areas to Adelaide, the Barossa and Mclaren Vale simply don't want their areas taken over by suburbia.
This is a very real problem for Mclaren Vale which is within the metropolitan area and major developments are taking place practically on its outskirts at Seaford Heights.
The Barossa is seeing development in Nuriootpa in particular and suburbia creeping out from Gawler and is likewise not keen to see grape growing areas either built out or priced out of reach of growers because of land rezoning leading to rate increases.
The development in the Barossa is to support industry in the Barossa rather than as a dormitary area for Adelaide.
If the renewal of the railway, a billion or so to bring the track up from derilict to 100kph plus passenger standards, a couple of hundred million for a (small) railcar fleet, plus the direct costs of running the service, fuel, track access and wages, leads the Barossa to become a dormitary suburb, then of course the locals are going to react unfavourably to rail seeing it as the city intruding into their patch.
The LinkSA bus services from Goolwa and Victor Harbor are much faster than the train service ever was and serve 2 major shopping centres and a hospital before arriving in the centre of Adelaide.
The major handicap for the train is break of guage at Mt Barker Junction. The present line might be suitable for the leasurly tourist services it carries, but hasn't a hope in hell in competing with the diect via the Victor Harbor Road bus services.
There is some call for the restoration of rail services. This seems to be coming from some along the Burra line which has poor public transport services.
Those services are poor for one major reason, lack of population so I won't hold out for the passenger services to be restored.
