I have a few baseboard structures that sit on top of the main tables. because of their box structure they are rather noisy when trains pass over them.
I would like to fill these structures with expanding foam in order to make them a little quieter. Blocks of rubber or foam are not, I'm afraid, an option since I can't get these inside the structures.
Has anybody any experience of doing this and any recommendations as to the type of filler?

Re: Quiet Please!
you could try the spray foam from DIY stores f filling cavities around pipes in the wall. Be careful as this expands on contact with the air and so needs to have some release for the air and excess to escape if used in a confined box like sructure

Without free access to air, the foam often remains liquid and does not fully set.
The alternative is to acoustically de-couple the structures with a sound absorbent gasket.
Something I learnt from restoring an old car- those annoying squeaks and rattles often ceased with a very thin piece of cork.

Following Tim's comments about a thin cork gasket, maybe you could simply slip some thin cork between the boards and the table, or even some thin rubber sheet. Might save you having to fill the baseboards with foam. Also, rubber underlay will help.
