| I built a small three module N scale layout used at our town's annual Christmas Hands On Train Display. We let the kids take the throttle and run the trains on four layouts in varying scales. My Unitrak layout holds up well to this use, except I have not found a good way of securing the track to the pink foam base covered with plaster cloth. I tried Liquid Nails any it seems to attack the plastic and not hold well. Any suggestions? |

| I use Titebond [original formula, not waterproof] yellow glue to bond track to foam. It takes a while to dry, but you can change the track later without damaging it by spraying it with detergent/water, letting it set a few minutes, and lifting it with a putty knife. |

How large is the layout?
I would just snap it together and let it float on the foam
it hardley moves if at all |

When I built my Z scale layout with MTL's Z scale Uni-Clone track I used clear silicone caulk.It worked great.
When I build my new TTRAK modules using Uni-Track I will use the silicone caulk for that too. |

there is a special type of liquid nails for use with foam. It is marked on the tube as liquid nails for foam. The world's greatest hobby dvd shows this method using Bachmann EZ track. You might be able to even find the clip on you tube if you do a search for it.
Silicone caulk mentioned by Catt is another good choice and I believe is the method used by David Popp on in N waterbury industrial district. The brand he uses is Dap latex caulk and this video clip is availible on Model Railroader's website. Try this link: http://www.trains.com/mrr/default.aspx?c=a&id=2681 |
More!!!!! In Nscale, please. |

I've used Liquid nails for projects. It's safe for foam. My favorite now is latex caulk. Just pick up a tube or two of gray caulk. Place a decent sized dab on each of the little cast in screw risers and stick to the foam. If it's a short piece with no screw riser, place a larger dab into the low area. Make it enough to come above the bottom of the track when inverted. Push that down on the foam until flat. Any that oozes out can be easily wiped off with a damp rag.

| Thanx to all for the suggestions, I tried Liquid Nails and was not completely satisfied, but I don't think I used the latex version. I'll try that, and also the clear silicon caulk, to see which works best. One of the greatest things about this forum is the help offered when a question is asked.[:-cowboy] |

| In the underside of the track are mold holes that also work well by adding a drop of CA and placing a small brad nail in the molded hole to spike down the track along the track center. This holds it in place and you can still add a little glue too. I guess sort of redundancy in case there is a glue problem. |

| Someone on here not too long ago mentioned hot glue for holding Uni-Track. I'm not sure if it was foam he was attaching the track to or some other material. The poster said by wetting his finger he could remove any glue that oozed out from under the track. I'm planning on trying this on my layout at some point. |

I tried Liquid Nails for foam and it worked pretty well. I only applied to two or three spots on each of the three modules and the layout held up pretty well to kids running trains, and to moving, assembly and dis-assembly. I guess I'll just check it out and add a few more spots next Christmas season. Thanx for all of your suggestions. Happy New Year to all of you. |

hot glue (woodland scenics gun and glue is not hot enough to melt foam)... applied in thin layer at base of track (thinned out with tip of hot glue gun), in small half inch sections (not too much is needed)... while holding the rail heights uniform with your hands and "eyeing it up"... glue dries fast, rail height is perfect.
it takes a little practice, but the result is fast and good.

I use a low-trmp hot glue when I was adhering the Unitrack while building the "new" JJJ&E.
You just place some hot glue under each corner of the Unitrack roadbed.
Stay cool and run steam....[:-shades][:-shades] |

Hot glue as well. I get it positioned and hold it in place with 2 straight pins at either end of long sections, and when its placed right, lift it up with an old screwdriver and use hot glue spots at the 4 corners. If it seeps out keep a scrap piece of foam to wipe the seepage. If you have to lift the track the hot glue will generally just pop off with your fingers or a small screwdriver. Never hot glue any turnouts.
