Forum:How do i make an infobox with not all the atributes?

Is there any possibility to create an infobox template which doesn't introduce all the atributes on my article's infobox?

I've tried on this article, using this template.

If i`ve removed routes 2, 3, 4, 5, 6 from the article infobox code, it imported automatly from template the default values, instead of not displaying them.

Could anyone give me a hint, or an advice?
