Fortunately, with Mark moving towards mainly aluminium construction, none of the parts seem to have been affected.

The box containing the track links was at the bottom of the main box, and has disintegrated, but again, the links themselves are OK.
Hopefully, a couple of hours in the sun will dry off the parts and again, I can re-box them in a plastic box.
