I've been having a holiday with my grandfather in port kembla and we've been chasing trains all over the place. Some may say that the best tool to have when doing this is a map but the best tool that I've been using down here is my iPad. It shows all your normal maps with the black and white line showing the railway line but it can also give a satellite picture of lines you never knew existed. You always know where you are whith the GPS helping you out. With this in hand, we've had a great time chasing trains around the port and also the southern highlander around robertson. Any other techniques people have out there?
