David needs your feedback on joining foam layers and also share a quick model railroad tip:
“Can anyone tell me what does one use for a quick cement to secure foam together in layers?”

David also has a quick tip for fellow railroaders:

Tip — I am using one layer of 1/2 inch foam with light pine re-enforcment to cover tracks going into tunnels, So I can remove the whole mountain to clean track and fix a derailment. Seems to work very good and is light to handle. The mountains have been made on top and the whole thing is removable when needed.”
