Some may see some train tracks that could be anywhere. Others will identify the greater Melbourne location in five seconds flat. So where are they? If you know, explain what is being seen. The photo raises a question in my mind. If I was a user of the service in the morning peak, travelling from the top of the picture to the bottom, I think I would know the answer for sure. I'll see if anyone answers the question before I ask it.
Later Edit: The question is, do the express trains all use the Frankston line tracks?
