2307-2334 lead a loaded coal train along the flyover between Dutton Park and Buranda. The dual gauge flyover diverges from the Sydney to Brisbane Line at Dutton Park, crossing the Gold Coast/Beenleigh railway, then the Cleveland lines before continuing towards the Port of Brisbane at Fisherman Islands. Despite being dual gauge the line has seen very little standard gauge trains since the rock trains for the port expansion project wound up several years ago with most traffic being coal trains from the mines west of Toowoomba.
Also, note the free couch. If I had an offsider with me at the time I would have been very tempted to move it up to my viewing location as seating options were limited.
