The grain silos at Goolara a few kilometres north of Theodore have been as far as trains have travelled since the branch lost regular freight services.
Are they in use?
Going by the satellite and street view photos which are a few years old, the silo's look in partial use.
When I lived in Gladstone 1998 to 2009, every time I drove out that way I never saw any evidence that a grain train had been down that way and if they did it would have been very rare.
The railway full branch itself was remove I think +10 years back.
The line beyond to Theodore (town of less than 500) was closed in 1993 with a farewell DMU tour in 1991 (I believe).
Its hard to tell on the Sat photos, but I think the line from Moura mine to the Moura grain terminal has also been removed. In an older satellite photo, there was a train in the silo.
For those not familiar with the area, the whole grain thing in CQ, especially inland from Gladstone, the Biloela, Moura, Theodore area has been a colossal failure. Spend some time on Google Satellite photos to check it out. When I arrived in Gladstone in 1998 I first thought the port was a major grain export terminal, large silos, 4 unloading tracks, all sparked. But the two grain trains used to sit there for weeks and not move.
The grain silo's had been partially leased out to other users and some unused. A grain train arrived a dozen or more times a year, mostly from the Central Line, in a good year. I lived in Gladstone for 12 years, I probably saw the AK cars there more often than a grain train.
The grain terminals in the Moura district are mostly old, small and rarely used. The few hundred thousand tonnes of grain harvested each year is either used locally or trucked to port. Having lived near the highway for some years on outskirts of Gladstone I barely recall seeing a grain truck. I would need to check, but I think much of the CQ grain now goes via Mackay. QR cut the north parts of the old Moura valley lines in early 2000's, maybe earlier, leaving the tracks to Moura, Goolara, Jambin and Biloela, but very limited traffic. We stopped at the Jambin silo's in 2003 and the line was clearly kept open, but very rusty rails and silo's built for another era of train size.
Moura silo used to get I thought a good load and deemed the most viable for rail being almost 200km from port on mostly modern alignment designed for 26t/ale 80km/h coal trains, but going by the Sat photos, I don't think its rail connection has survived. Certainly the track was never shinny when ever I went past although it was clearly maintained. The whole Moura yard was amazing, tracks everywhere, 3 way junction, but all a legacy and left for the Qlink days when they used trains not trucks?
Biloela's final freight was actually beef, 3 x a week a non full length container train used to run past our house up to Bilo, its only about 6-10km from main into Bilo, but eventually QR pulled the plug in late 2000's and said not viable, its cheaper to truck to Rocky 100km north and rail to Brisbane or Townsville from there for export which I believe may still occur.
While the likes of Freightgate are awash with shock and all and claim cancer etc, unfortunately in this part of the world, the loss of rail is hardly unexpected and realistically did well to last as long as it did. My only disappointment would be if Moura grain silo has indeed gone 100% truck. Being so close to the Moura coal mine the track MTCE is SFA and the corridor into Gladstone or at least the mainline for transport to Mackay terminal is as good as it gets for regional freight being modern alignment built for 80km/h 26t/axle coal operations.
Qmag in Rocky was/is leasing some of the older grain silo's in Gladstone and when I worked there doing ship loading, I spoke with a few old timers at the port and asked what was this all for? They basically said on the back of good weather and again another proposal to increase irrigation, the Sir Joe through money at increase grain infrastructure, but then it didn't rain and the irrigation scheme was axed, again.
Freightgate should also read what others have said about the services to Theodore and that for almost the entire lines life it was nothing more than a 1-2 weekly small mixed with an average speed of 20-25km/h just to get to Rocky. The line was actually extended a further ~20km, but never used as the whole thing including the track to Theodore was built on the back of the Nathan Dam irrigation scheme that never happened. So is the line closure a cancer or was the lines construction and operation for 70 years the actually cancer?
Ironically the Nathan Dam is back on the agenda, but the project has been stated to not be for local use, only retaining existing demand and not intended for irrigation, but rather for the real money earner, coal in Surat basin!
