I was in Sydney last week, and being from the country I have a few questions about the Sydney network that I thought someone on here might be able to answer.
Firstly, I caught a number of North Shore Line trains (as I was staying in a friend's unit in Wollstonecraft), mostly K sets with the occasional S set or Tangara. On the S and K sets I noticed a noise coming from underneath the driver's cabin, sort of like the sound a fridge makes when it is cooling itself down, only louder. It was intermittent and would start up occasionally before turning off again. Does anyone have any idea what this might be? I know the description is a bit vague but it is the best I can describe it.
During the week I often travelled into the city and got off at Town Hall. I know that Platform 3 is one of the most busy in the network during the morning peak, with a lot of people getting on trains, but why is this? It makes sense that a lot would get off as trains have come from the Western Line, but why would so many people get on a train leaving the city in the morning?
Thanks for any answers you can give me - they might be silly questions but I hope someone can help me.
