Our local Club in central Iowa has got started with Modular Railroading. So far we have built 8 curves, 45 degrees each that will make a 16 foot diameter double main line. These were financed by our club, CIGRS. Members are invited to build a 4 foot section to match the main line and decorate as they wish. We already have 12 of them built. We have set up at least 3 locations with good results. The issues we are questioning are, weight of each piece, they are pretty heavy. Ballast, we started with real crushed granite, adding more weight. It is also breaking loose with each move. Storage and transportation? We have made the corners stack-able on a cart with large casters that move pretty well. Would like to make the 4 foot straights stack-able, but want structures on many of them. Should the buildings be removable? How do we deal with them? What would make a lighter weight, more durable ballast? Wanting to add a storage yard.................. I know Del Oro Pacific has a huge set up, would love to see what they have going and how they move and do storage.
