I'm ready to attach my layout on a 4x8 sheet. It is now atop a 1" sheet of Owens Corning FOAMULAR. 

Should I slide another 1" sheet underneath before things are attached?  I know much depends upon what I plan to do with scenery, especially water.  Any other considerations?

THanks for any help

I'm attempting to finalize a 4 'x 8' layout.  I'm trying to decide on a small yard layout 3' x 3' (approximately).  I have a double oval layout.  The inside oval will have a left turnout mid-way down the 8 ft. dimension, which would turn into the yard.  I have assorted 18" curved and straight EZ track, two left DCC turnouts, and one right DCC turn out.  I also have a couple of rerailers I'm trying to position in the most effective way, as well as two uncoupling magnets I need to attach to straight track and locate strategically in the "yard."

I would very much welcome suggestions for this small yard.

Thanks for any help you can give.

I have a 4x8 sheet of plywood with a 1" foam sheet underneath.  I'm using EZ Track.  I have an outside perimeter track that's flat and an inside one that takes a 3% incline using Woodland Scenics.  This inclined track does an over/under loop at one end of the layout.  I've used foam pins to stabilize the layout and test everything.  I'm still working with smoothing out several places in the EZ track, but for the most part this is what I want to commit to.

What's the next step? 

Here's what I'm planning.  I'll pin down the inclines to the foam board, place pins around the track at joints, and then run everything to make sure there are no glitches. 

Then I'll glue down the sides of the inclines with low temp glue, let it set, then glue down the track at the joints--or do you do the track differently?

After everything is set, I'll work with the landscape by adding foam boards to create the tunnels and the mountains.

Does this sound right?

Help!

I have an all-DCC system.  The turnouts and the crossovers work fine, and I don't mind controlling everything from the EZ Command unit.
If I buy a powered accessory (station house, lighted caboose, road crossing guards, etc.) do I power it by plugging into a jack on the terminal?

For my two young grandsons, I bought a Bachmann Echo Valley DCC set and put it on a 4x8 sheet in the basement.  I researched various layouts 
and bought extra track and turnouts to do the double track one I have settled on.  I have a better locomotive coming for the switching yard I'm planning.

What accessories would you guys recommend for young grandsons who have an intense love of working with trains, trucks, front loaders, etc.?  They love to load freight cars with beans, send the train around the track, unload it, and move it to a connected adjacent play table.

This old grandpa would appreciate any help.

Thanks.

A couple of weeks ago I bought a Bachmann Echo Valley DCC set for me and my grandsons to enjoy.  I had the bright idea of buying a 4% incline from Woodland Scenics.  The little Echo Valley engine will pull the grade, but with no more than its tender and a couple of cars.  The grade is 4" over an 8 ft. stretch.

I have a Southern #2735 diesel coming tomorrow.  I am assuming it will be able to pull more cars up the incline with little problem.  Am I wrong?

Would a 3% grade work better?

Thanks for any help.

I'm helping my young grandson with his first train set (a Bachmann DCC Echo Valley). I know little, but I'm learning. 
A basic question: Is there a problem using Bachmann DCC crossovers to connect an outside oval with an inside oval.  It sounded simple enough, but I called a Bachmann tech representative who talked about electrical problems if I did so.  He recommended 4 turnouts to do that connection.  It sounds like weird advice to me.
Thanks for any help.
