I always thought that would be the reason for the BSC Mac-Archive. I do not really dare to share stuff without permission of the author and it seems like this guy already has them.
I'm not quite sure if it all worked so well, the new stations still seem to behave quite strange. Although SimGoober wrote his stations are now freight-enabled, it seems that they are not. This might or might not also be a mac-specific problem but I did not figure out how to set traffic-properties with this tool. So, still, can anyone help me with that??
