And the rest Sulla. Not unusual for 3 trains to be on the Rolleston branch at one time, one heading down, waiting at Memooloo, one waiting at the BLB outside the mine, while the third is loading. In addition, you could have anything up to 6 or 8 anywhere else in the Blackwater system, either headed to RG Tanna, or WICET. They have really ramped up output since WICET has come online.
Its DTC territory, and electrified, which I am fairly certain is unique in Qld. Most of the run from Kinrola to Rolleston is undulating countryside, with no real climbs or descents on the trip. No air needed on either trip, the 37/3800 DB easily handling the couple of descents, provided you set your train up correctly. Air only really required if our going into the loop at Kenmare loaded. MLPI installed here.
Its about a 8.5 to 9 hr return trip from Bluff, depending on other traffic. As stated above, most trains since electrification are standard FMB electrics for Aurizon. PN runs some trains down there, using their standard diesel consists.
Branch length is about 106 km, including the balloon, from Kinrola.
