Mildly confused....track underlay...
« on: November 05, 2012, 03:53:45 PM »
Ok...I've finalised my baseboard construction and layout planning.

My next step is to choose a material to underlay the track.

Generally do forum users have a preferred material or method or do some not even use an underlay?

I also understand that by using a form of underlay buildings close to the track will need to be raised slightly to compensate for the elevation in the track.

Thanks - what is your preferred material for a baseboard?

I've used nominal 2 x 1 for the baseboard covered in Sundeala, then added commercial grade rubber over the top that will be trimmed where no buildings etc exist.
To my mind, if you raise your track on underlay, you will need to raise platforms etc by the same height - dependent on their construction of course.

I avoid underlay. It tends to degrade over time and doesn't look as good as ballasting with scatter materials.

The underlay has its place - its a good way to get a ballast look with Peco track if building something to get the hang of things and you are not confident to do the "fancy" stuff yet. If you do just be careful to pin the track gently to the ballast. What you don't want to do is pin it down hard as the foam will push up and your track will end up far from level.

We all know NN fetish for rubber  :smiley-laughing: but I find cork much better, like NN I lay it all over the baseboard and trim where there are no buildings.  As it's easily cut, you can make cut-outs for things like signals, loading gauges and buildings so they don't appear plonked on top.  :)

I don't use underlay either.  I used the Peco foam years ago, and realised how awful it was!  I have used other methods as well, but I prefer the track to be fixed to the MDF baseboard.

When it comes to track underlay, I've experimented with Woodland Senics Trackbed and cork neither of which I really liked. I've now gone to lay straight to base board (9mm ply). I might use some cork under one rail if I'm creating a fast curve but that's all.

And rather than pins I use Copydex to glue down. If you need to relay you can lift and rub off the dry Copydex from both rail and baseboard.

I'm experimenting with using 6mm Depron sheets on Ivebridge. It's a sort of flexible polystyrene sheet that's used for wall insulation. You glue it to your baseboard with copydex and just stick everything on top. It's also useable like you'd use cardboard to build up scenery etc and I've even used it for my Scalescenes card models :)

One advantage of using a sheet of Depron or other underlay is that you can cut into it if you want to recess a building by its thickness. This means they look less like they've just been stuck on the ground ;)

I use sheets of insulation cork that is relatively cheap here, glued directly to the  plywood baseboard. That way the buildings etc are still level with the track. The track is then glued using a PVA type adhesive. Plus when I change my mind (about once a week after track laying started) the track can be easily salvaged.
Some days its just not worth gnawing through the straps.

Generally how thick should the underlay material (cork, foam etc) be ?

It depends how much you're trying to reduce the track noise and also what the underlay is stuck to. For instance if you're building onto a very solid table where there's not much resonance, you don't need much underlay to dampen the sound. If you're using thin hardboard on timber frames, that acts like a drum skin and can amplify the noise, so more underlay is handy.

I'm happy with 6mm thickness Depron on my hardboard/timber baseboards, but the layout's in its own room and has other sound dampening under it, so noise isn't a problem.

It is likely the layout will be mounted Birch Ply (6mm) with a timber frame possibly with some form of sound barrier between the ply and the track (cork???).  The layout will not be in one fixed location in the house, initially but likely to be constructed and worked upon on the dining room table.  Not yet found a temporary location to store it while not being worked on!

Not ideal but the best solution for now... :thumbsup:
