Possible with a model railway you could provide some sort of a fabric
cover ?

and make sure it is natural fabric - cotton, linen or wool - all of which
can absorb moisture.

Wool is the best for 'managing' moisture, IIRC.

I saw it claimed on a website selling irish wool for roof insulation -
basically the claim was it lessened the risk of rot in timbers by buffering
some degree of moisture before it condensed out elsewhere. Could see a
reason to disbelieve it - though it wasn't stated exactly how much water a
given amount of wool could absorb whilst remaining dry to the touch at
various temperatures (if temperature has any bearing).

Mind you - my BCO still wanted the usual ventilation paths and spacings when
I was discussing the possibility of using wool...
