I have tried the invisible ink (IR reflective thing), but I cannot distinguish it from grey surface. Maybe, I could turn the thing around to see dark portion as a line and then I could see it on white surface. As this would only have a value of cute experiment at the moment, because white streets would look very odd on model train layout, this will have to wait till I have less crazy complicated stuff on my mind with inertial navigation and eCompasses .
If you mean the .rar file, then the answer is no. There are 5 or 6 files if I remember correctly and at least one of them is too large to paste. Just download, rename the file to whatever.rar by removing the .txt extension. Sorry for the trouble, but forum would not take .rar files.
