Here is an example:

tunnel=* [0x12 resolution 20 continue]

This would create a second line which you could use (with an appropriate typ file) to create a special overlay for all lines which have the tunnel tag defined. (This is theoretically a bad example, because lines with the tag tunnel=no would also be included, but this gives you an idea of how the feature should work).

As far as I can tell, people see to be using this kind of thing for tunnels, bridges, and one-way streets in particular.

- I can't say how the stop command should work differently from the default behaviour though.

- There are also issues with the line draw order, I believe, if you particularly want one line to appear on top of the other.

Hope this helps. Cheers
