A 2-car Xplorer set, running as HP68 from Hurstville to Maintrain (at Auburn) passes Campsie on the down goods line.
The 2-car set was doing crew training runs on the metropolitan goods lines for the New Regional Fleet test crew.
Funnily enough, I planned to use the overpass to frame the lead cab of the train BEFORE it entered the shadow (as the sun was in the western part of the sky at this point), but as I was trying to hold the camera over a fence at the time, the focus went wonky. At f2.8, this was quite noticeable so this was the only composition in focus. Thankfully, I don't mind it!
