I have finished building the framework for my layout. The size is approximately 12' x 13'. What would you recommend as the material to use for the top? I was thinking plywood, but what other materials might be better? Has anyone used 1" thick rigid foam insulation board? If plywood, what thickness?

Hi Ron I think plywood is the best approach with 3/8 (10 mm)thickness in a frame structure This is a good compromise for HO between weight, space between levels, cost. The frame structure provides for solidity, access to multi-layer layout and noise reduction (foam or cork under the track is not needed with C track. My structure is made of "beams" of 5/8 (15 mm) plywood mounted vertically (5" wide) in squares with removable feet with casters & brakes Here is the look of it before landscaping With landscaping there is no noise / resonance Here it is with some landscaping Cheers Jean |

Jean Thank you for sharing the video of you outstanding layout. It looks like it is running smoothly with lots of action. What DCC system are you using?

12mm MDF would be the only alternate I'd recommend to ply.

Hi Ron Originally Posted by: Mr. Ron Thank you for sharing the video of you outstanding layout. It looks like it is running smoothly with lots of action. What DCC system are you using? Thanks Ron. The layout is using MFX and MM2. It operates from a CS2 (60215) a 60101 (100W Märklin power supply) and is driven by Rocrail. The system is Märklin 3 rails (detection by contact rails. The wooden structure is so that there are 2 large modules forming a T and a small appendix. The Modules are 2.45m by 1.25 m and bolted together. The structure can support the weight of a person.

There are a lot of different types of plywood, some are heavy and have a solid surface into which it is difficult to screw something, especially small rail screws! Several years ago, I discovered an extremely light Ceiba plywood in which even the smallest screws can be easily screwed.   It is easy to cut and comes in various thicknesses and sizes. One plate 250 x 150 cm weighs only 10 kilograms!  The large layout of the Backo mini express was also made with the same material but slightly thicker. I used side and other load-bearing sides 10 mm thick and for larger surfaces and routes only 6 mm (with support).
