It is rendered. Please force your browser to reload the images from the server and not from the local Cache. In FireFox you can use Ctrl-R for this.

You have added 2 nodes to the map and tagged them as tunnel. This is not the way to do it.

What’s needed for a tunnel is a way. Split the way where the tunnel starts, and once more where it ends. Then select the piece where the tunnel is, and then add tunnel=yes, layer=-1. Don’t remove the highway tag, for instance.

Ups. I was tricked by the differnd widths of the rendering of the name… Sorry.
