Pictures or links for benchwork construction of modular sections

My modular club uses quick grip bar clamps to hold the modules together.  No tedious twisting like wing nuts.

We use clamps, but I recommend you consider alignment pins in each section and then you could use bolts.  It's not like you're going to be taking them down repeatedly.  FWIW, our modular club also uses clamps, but we assemble and disassemble a lot.

Jim,

Our club also uses C-clamps to secure the modules together and thumb screws into t-nuts to attach the legs.

I am using hex bolts and t-nuts in my new layout, as shown below.  I use them to secure modules together and to attach the legs to the modules.  A socket on the drill make short work of attaching and tightening.  Plus, it draws the t-nut tight.  I recessed anything along the front so as not to interfere with the facia.

For a requested link Google " Freeman Manufacturing brass square dowels".  I use a lot of them for many purposes.  Mostly the #4 size.  When I built the TAS modular layout they were that which made the set up easy,

You can clamp or bolt once aligned.

For requested pictures I offer:

For use in module framesFor use in lift outs

I also solder leads to the top and bottom brass dowels to provide wireless track connection for track power applications.

The LCCA modular systems uses rotolocks, which are also called coffin locks.  You  can read more about it on the Lionel LCCA Fastrack Modular Manual, which is on LCCA's website.  

My understanding is that coffin locks are routinely used in theatrical stages for fast set up & disassembly.
