The day trip was simple... take the Overland (for the first time) from Southern Cross to Ararat, spend the afternoon in town and then return on the evening V/Locity.
The afternoon freight was smack on time. But then this happened.
This is the RG331 QR Rail Grinder. ARTC contracts it to freshen the rails around their network. I had heard something grinding away and headed for the rails... but had missed it. Fortunately it reversed and re-grinded the same location. Of note, it has quite a strange horn.
Was a pleasant surprise... have only ever previously seen it staged in sidings. Here are some shots from Yass Junction, way back in 2009.
