I wondered why those locos needed all that water when they had a small coal bunker. Those coal hoppers are very cute. After watching them being unloaded into a freighter, it occurred to me that Ben would have liked to model that operation. It's typical of coaling operations that appealed to him.
The area around Maitland and Cessnock is nice country and there are lots of wineries in the foothills. My wife and I spent a few days in that area a couple of years ago.
