There is an EMGS manual sheet that covers modules 6 . 6 . 0 . ( 1) written by the late Douglas Smith. I was thinking more on the lines of interconnecting two or three small layouts together, simply, in a straight line, occupying about 10 or 12 feet in length. It would be an exhibition managers nightmare to have to contact 7 or 8 members to bring their respective modules along. However I know of one members who alluded to the fact that he as going to connect two of his very small layouts together to increase scope and to cut down the need for fiddle yards.
It’s all food for thought.
