I have noticed alot of layouts have foam board under the tracks or totally covering the plywood. How are you guys fastening it with screws or by using glue? I think I'm ready to lay my foam down and wanted to see which was the preferred method.

I used hot glue for mine, gotta be somewhat quick about it, but after 2 minutes you can move on to the next step be it track, scenery, or whatever.
I had issues with the foam glue I was getting from Hoppy Lobby and Micheal's. I was contemplating using hot glue, but I just don't work fast enough. One of the managers of Michael's suggested using wood glue noting that when it dries the color would not match the Styrofoam. But it's easily paintable with little prep work and covers large areas at far less expense than foam glues.
I use Liquid Nails 'PROJECTS' to glue foam. See links - make sure its PROJECTS as anything else gets hungery and eats your foam! Projects is made specifically for foam products. Russ

I use wood glue and screws. When the glue sets up you can take the screws out and work your foam into shapes then for terrain, hills, mountains etc.

Project LN has this for setup:
Working time up to 30 minutes. Dries in 24 hours. Fully cured in 28 days.

I prefer LN also but I use the construction grade. It, to me, is faster and stronger. I am always in a hurry.

I've been using Liquid Nails "Panel and Foam adhesive" and it seems to be working pretty good. Yesterday the store had a deal on LocTite Foam Board construction adhesive so being the cheap sob that I am I decided to try it. Not happy with the product at all. This morning the pieces I used it on are still not bonded. I imagine once the adhesive is completely dry it will hold but it does not have the initial bonding strength of the Liquid nails, which allows you to move on to the next piece with in a few minutes. The Loctite product doesn't hold well in the intial application and when trying to add on additional pieces the prior pieces tend to slip out of place. I guess if your using foam nails and clamps that may not be an issue. But with Liquid nails there's rarely a need for that. So this cheap sob is on his way back to the store to get what works and allows me to be productive.
When stacking foam blue board for mountains I use 3M spray adhesive. Only because it's quick and the hot wire foam cutter goes thru it easy. I bought some of the glue from Hot Wire Foam Factory called styrogoo but have not tried it yet. They have a lot of products for working and finishing foam. I think its worthwhile to look at there web site or call on the phone they will answer. I usually don't fasten the foam to my bench work unless its structural.
Actually I am currently using the liquid nails for stacking foam. The reason I like it is though it's initial bonding is very strong it still has a pretty long working time and you can still make minor adjustments to the pieces placement during the first hour or so. I normally cut and fit before applying any glue. But there are times when you will have to make cuts later and the hot wire does have a difficult time cutting through glued surfaces. So one does have to anticipate this when applying the liquid nails. But,because you really don't need more than a 1/4" bead to hold twelve square inch pieces together you can easily determine how far the glue will spread and keep it away from where you may need to make future cuts, (sometimes). Sometimes not though but it is still possible to cut through the glued area with a little more effort. I guess I like the liquid nails because of the control I have over where I apply it. I'm not only a cheap sob I'm a messy one too. When stacking foam blue board for mountains I use 3M spray adhesive. Only because it's quick and the hot wire foam cutter goes thru it easy.
