That's the sort of map, that N3V needs, as it look like it can show different types of track in different colours.
Oh by the way, Philskene, I had to heavily edit it (most of it), as for some reason, I was having a technical issue with the editing.
Edit: Philskene, I've just downloaded it, and scanned it for security checks, but I've got a security warning
