Once upon a time I was into railway modelling. I never went to, but enjoyed reading about, the modular meetings where fans got together to set up a mega layout that none of them could have built individually. It was all based on the FREMO standard. https://www.fremo-net.eu/en/modular-systems/h0-scale/h0-europe/h0-europe-nem/
Obvisously, Lego has already created the connection standard for the Modular range, so my question is, would anyone be interested in getting together to create large modular layouts? With only limited numbers of official buildings, this would obviously rely on MOCs to create a large city. And if it worked, would it be welcome at the various Lego shows around tge world?
