The metal box is a large part of the problem, the windows are just usually the easiest way to get a signal into the train but if they increase the density or add a metalic coating obviously this is going to cause problems too. I've done large sections of NSW and Qld railways from yahoo imagery, while not 100% accurate it is the best way we have until some govt agency releases data or someone is able to get a trace. _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
