How much work must have gone into this animated graphic. Just brilliant, about the expansion and shrinkage of Victorian Railways. You begin to see it start to disappear in the 1970s and increased greatly after the Lonie Report in the 80s. Some time earlier in England came the Beeching Report, which lead to the closure of many railway lines.
So, go to the above website and you may have to click animate on the left.
I don't think an animated map has been made for New South Wales, but here is a static map for Sydney folk to see when your nearest station was opened. Included is the date when each station opened. Nice work by someone.
Below is a map of Melbourne's trains system. Our naming of lines is absolute rubbish because they keep changing the name. Both London and New York do line names very well, with London having names for lines and the name doesn't change, and New York names their lines with letters such as the A Line, not terminus names as Melbourne foolishly does. Nevertheless, I think our train map is easier to follow than Sydney's. Frinstance, how do I get to Hornsby. I catch the T1 line, but T1 goes three different ways. How do I know? Not that I really want to go to Hornsby.
Ok, no map of Melbourne. It is too hard to find the right one. I've spent enough time on it. But to give you a taste of what I mean, the St Albans line became the Watergardens line as the suburban system was extended, and is now the Sunbury line. The Epping line became the South Morang line and is about to change names again. It is so silly.
Go to this link and see how Victoria's country train system expanded and then contracted. The animated map is just a brilliant piece of work. Yes, I linked to it above, but I can't be bothered editing any more. The large gap on the right is the mountainous Great Dividing Range. For travellers, the final map is not as good as it looks, as a number of lines are slow freight lines, slow because of neglect.
