Below are 2 videos, one to show the structure of the multi-layered set-up, and one to show the noise absorption thanks to the landscape The track support in plywood ("GleisTrasse") The same layout with landscape Note: you will notice, that the layout with landscape (2nd video) is way less noisy and so the sound level of locos has been sharply reduced when compared with the first video. So, what I am trying to say is: - avoid if you can a large flat, plywood surface and if you really must have one, then inserting a thin foam bed may help - in a multi-layer layout, the noise is absorbed by the structure Cheers Jean

Trackbed of course, then ballast can echo noise and even exsentuate it, so choose one not made of plastic. Also the glue used can absorb and quiet the sound. What I used as an underlayment is good quality batted black, or dark brown or green vynil upholstery fabric. It worked under M track well, and C track. However, one track substrate is solid plywood, and one a hollow door. The solid is quiter. I thibk the space in between the inner and outer panels echos sound. The tracks running over a plaster embankment berm are quiet.

Like a violin or a guitar (made of wood) the noise is amplified to a degree. I do not use screws to hold track down, so I dont have a noise problem. Only the swishing of wheels on rail. See my layout idea here: https://www.qldrail.net/altkloster/softlysoftly1.htm Kimball

I have found a roll of 3mm underlay for wooden floors in my garage, and which is supposed to be sound deadening, so I might well lay that across all of the ply and then work from that. Once again - thanks for the help Alex

Then I can use short tacks to attach track to it, without them going thru to the plywood and transmitting vibration & noise Edited by user 17 July 2023 23:20:07(UTC) \| Reason: Not specified

		Take care I like Marklin and will defend the worlds greatest model rail manufacturer.

Joined: 28/09/2019(UTC) Posts: 110 Location: Rogaland, Haugesund		Hi Lots of good advice allready👍 On my layout I made the mistikake of using lots of plywood plates creating a guitar box. Should be used under the tracks only. For remaining use styrofoam or aluminun net with plaster. I also used cork under the C tracks. Maybe ok first year but became hard as wood quickly. I Think syntetic is better. And use elastic glue. No screws. Regards Thor

I have added a bit of acoustic insulation to my layout, but it has been a secondary issue to my car.
