Comprised of five locomotives and 73 wagons stretching 1.3km (0.8 miles), the train left the town of Narrabri on Wednesday.
It later unloaded its cargo of wheat bound for markets in Southeast Asia at the port of Newcastle.
Drones shot video of the bright yellow train as it snaked its way across the Australian countryside.

That's a lot of porridge :D

I took a video of a train in South Africa, 75 wagons, they seem to be quite common here.
