Yesterday I did some experimental glueing down of the cork strip for the upper loop. A quick examination this evening showed it had worked as planned so I've now finished off the main track of the upper level.

The upper station loop and siding are still to come but I'll wait until the glue sets.

Here you can see a photo of the cork as laid. The nice thing about doing it this way, is that it requires no compression to stop it from warping.

On Friday, I hope to complete the passing loop and siding in the upper station, then it's on to getting the supports for that sorted out. A good use for all that wasted wood from the upper board....
