A scenario plan for the Hobart Light Rail Metro by Seán Deany. He is a former resident and regular visitor to Hobart, currently living in Melbourne and transport advocate and novice transport planner.

In preparedness for challenging times ahead – when concerning increased global warming and decreases in fossil fuel supply, a low impact economy is now essential and fast becoming a pressing need. One way into achieving this could be better transport network planning leading to a major retro-fit of our cities.

Light rail transit (LRT) is one of the fastest modes of public transport infrastructural development worldwide. Its origins go back to the late 1960s and 1970s when a number of German cities in particular coupled trams and ran them on fully or partial ROW lines. LRT became an effective and economical method for meeting public transit needs through pre-metro or semi-metro transportation systems.

In Hobart there has been much discussion about reintroduction of trains or LRT to the city and particularly its northern suburbs. The HNSR (Hobart Northern Suburbs Railway) would run battery powered trains from Mawson Place at Constitution Dock and out to at least as far as Granton along the Main Line rail corridor. After much anticipation from the public, there is the PB (Parsons Brinckerhoff) Hobart Light Rail Cost Estimate: Report 2 of May 2009 made for the Tasmanian DIER. Their study is for overhead power LRT vehicles to run from the University of Tasmania to Bridgewater, via the Hobart CBD, inner northern suburbs and much of the Main Line rail corridor from Moonah and beyond.

While any one of or even a combination of these two proposals would be a positive step forward into the introduction of rail guided vehicles in Hobart, Seán’s scenario model is for a fully integrated LRT network for Greater Hobart.

The envisioned Hobart LRM (Light Rail Metro) in its entirety would be a north / south / east running LRT network (standard gauge) totalling 50KM in route length. The network would have up to 45 transit stops / stations in total. In his scenario proposal for the Hobart LRM there are 2 lines – these being the Green Line and the Gold Line. The Green Line would serve the entire north / south axis of the network from at least as far north as a Bridgewater Civic terminus to a Kingston Central terminus, via the CBD and the University of Tasmania – Sandy Bay Campus. The Gold Line would primarily serve the Eastern Shore suburbs – running from a Rokeby Village terminus, via Rosny Park and a new Tasman Bridge into the CBD, from where it would share the Green Line alignment between a sub-surface Hobart Central Stn, located beneath the Elizabeth Street Bus Mall as inter-modal change and as far as a Glenorchy transit stop.

The Hobart LRM would therefore incorporate a network of up to 5 bi-directional rail tunnel segments, totalling up to 6.65KM in network length. These would be composed of 6m diameter bore / cut and cover tunnelling to enable a seamless transit route under the Central Business District. There would be 5 micro-metro sub-surface stations in total – North Hobart, Warwick Street, City North, Hobart Central and St Davids Park. Tunnelling would also allow for LRT alignment from the University transit stop to the Southern Outlet at Proctors Saddle from where the line would run en route to the Kingston Central terminus.

The Hobart LRM would serve as the main transport artery for Greater Hobart, serviced by pulsed timed feeder buses, allowing rapid interchange and importantly transforming the Tasmanian capital into a truly Transit-orientated City.
