Autumn or winter?

This picture of railway track was taken at Emu Plains station in Sydney, Australia. We were heading to Blue Mountains and were waiting for the regional train. It was actually still winter when this photo was taken, but the colour from the surroundings looks as if it was taken in autumn. I probably would not get this kind of effect in autumn as it is very dry here until the rain comes in winter. Even so, the rain might not come every year. But this year, we have been blessed with heavy rain, to the extend that Hunter Valley was flooded for several days!
