I am building my first layout and started laying flex track on Woodland Scenics foam roadbed which was placed directly on the 3/4" plywood benchwork. The combination seemed to be very quiet until I glued it all together. Once the glue dried, the sound of a running train increased significantly. I am wondering if I simply used too much glue, but there are no instructions with the foam so the modeler is left to do it on his own. Some literature suggests that a sound absorbing material like Homosote should be installed between the roadbed and the benchwork, but I found that Homosote, celotex and other like materials are all too soft to use for layouts. They don't take spikes and are difficult to cut or shape without falling apart. Does anyone know of any new materials out there that can be installed between the roadbed and the benchwork to reduce the sound of running trains, or is this extra layer of material even necessary. Is there any literature out there that addresses this specific problem? I would appreciate a response from any modeler that has an operating layout and hear how he solved this problem.
