I chose to use foam as the baseboard of my layout. I started experimenting with this in 2008 (Photo). This actual track on the test rig was only pinned in place as it was never permanent.
- Foam base is great to lay my Peco code 75 HO flextrack. I can easily pin it in place using ordinary dressmaking pins. But you can’t nail it down.
- Instead, I use an adhesive, LATEX CEMENT and I buy it from carpet suppliers or carpet layers. I take a 1 or 2 litre plastic container and get it filled for say $10 or so.
- It needs to be thinned with water to a consistency of milk. I originally thought it would need to be thicker, but the thinner it is the better it penetrated under sleepers etc.
- What happens if you change your mind and want to move something? It is actually reasonably easy just by dissolving the dried latex – see the last photo.
- This foam roadbed is lightly cut down the centre to make it easier to lay curves.
- The other advantage of gluing the track to foam is that it provides an improved noise barrier.
- That is lessened of course when the track is ballasted but I am experimenting with very dilute latex as a ballast adhesive.
WHEN THERE IS A DISASTER:
Yes, yes … I know if I am flooded out, the trackwork may be in trouble. But the bloke in the house across the road will really be in strife. The peak of his roof is lower than my floor!
