Hello again guys
An HO Modeler and rail fan named Tim Warris is the fellow who built that operating CNJ Freight terminal layout - and here is a, his, webpage with history and photos of how this great layout came to be constructed. Most ALL of his track work is hand laid including all those special crossings and switch tracks. Here is his website link URL -- very interesting --- a must see !
