If we limit our discussions to what's most urgently needed, it's harder for us to avoid the short termism that's come to dominate DPTI's decisions.TorrensSA wrote:The Gawler line is 42km long and the Seaford line is 36km, I don't see why people are calling for a third track on the Gawler line and not the Seaford line. Both don't need a third line, what they need is regular services and an underground city tunnel linking the two up. The Gawler line also has no spur line, so even less need for an expensive waste of money third track. That money that could be used for the tunnel or extensions to Aldinga or Gawler East or Roseworthy.
Also, there are already 3 tracks (and more) along much of the Gawler Line. Yes, they're owned by ARTC and are the wrong gauge for our suburban trains - but our trains and track are gauge convertible. Once the Northern Connector Railway is built, is there a better way to make use of the old route?
Indeed there are a lot of sidings and vacant railway land, so for most of the stretch between Islington and Mawson Lakes, it looks relatively easy to add extra suburban tracks without impacting operations on the ARTC tracks
