Semi-permanent layout construction allows for changes/modifications to layout.

No reason to be bored if you can modify your layout from time to time.

This approach uses benchwork that can be easily reconfigured. Although it would not be considered a "modular" layout it does provide for expansion of the overall size by adding new sections to the layout.  All wiring is made using color coded wiring harnesses which permit plug and play interconnections. All connections to the track use 16 gauge "bullet" style disconnects.  Each cable also has a wire designation label that corresponds to very detailed wiring diagrams. This makes trouble shooting and modifications easy.

This modular benchwork design is not compatible with modular layouts set up at shows since it is designed for an elevation of 48 inches. The benchwork is modular but NOT intended to be taken down and reassembled at shows, etc.  It is a semi-permanent layout that can be reconfigured by adding more modules as necessary.

"Modular" style benchwork. No nails are used.  All attaching hardware uses #10 hexhead bolts and nuts. Table construction uses 1x4 and 2x4 lumber. All benchwork is "color coded" so that matching sections are easy to identify.

I agree with the "modular concept" for layout construction. My layout is about 2 years old and I built it using  frames of 1x4s, braced and covered only with Homosote.  I wanted light weight but stable construction using multiples of  standard lengths of lumber.  It is all bolted together and the self-tapping screws hold the Homosote down.  The widths are such as I can reach  most of the layout from the edges. The legs are 2x3s  with no bracing.  Height is 33" so I could get 3 legs out of each 8 ft. piece of lumber. So far it has proven to be stable, quiet and nice to use.  If I built one over again  and had the time I would go even further with the modular concept. Of course, I don't have heavy plaster mountains and multiple layers of track but I knew that wouldn't be an option. If I did build mountains they would be of light weight paper mache construction. Layout construction and design is an interesting part of model railroading  and what works for one person isn't necessarily  good for another.
