Remember this idea?

Readers of this blog may recall a long term vision I imagined for bringing Adelaide’s suburban rail system into the heart of the city in the same way many of the rail systems in other Australian cities do.

Yesterday the SA Government announced investigations to undertake a study into a similar plan to the one I envisioned in linking the northern (Gawler) and southern (Noarlunga) lines of the network and providing a continuous north-south rail corridor across the city.

There are a few differences of course. The route would have new stations under Pulteney Street/Rundle Mall and Victoria Square (east-west) rather than Gawler Place/Grenfell Street, KWS South and Wayville as outlined in my version of this vision. The line would reconnect to the Noarlunga line north of Keswick rather than at Goodwood. Estimates of the cost of building the project are put at between $2 billion and $5 billion.

Also, it is worth noting that this would be a long term project, as it does not make sense in building it while the rest of the system continues to be improved and electrification completed, as it is not feasible to run diesel trains in deep level tunnels such as the ones discussed.
