I agree on the liquid nails.   I am in the process of adding to my layout.  In that process I am removing a lot of the foam i put down years ago using liquid nails.   It is tough to get up sometimes.  So just be aware if you use it use what you need and little more just in case you ever decide to have a do over.

Good Day;  I'm new to the forum.   Wondering if anyone has seen or knows of a site where pictures of actual train displays at Christmas time exist?   For examply the local Sears store from my home town used a D-106 but changed some of the operating accessories.  They had an icing station on it.  I would love to find some pictures of it but know they probably do not exist or do exist but in a personal album somewhere that will never be seen.
I have many of the books of factory layouts and many show the D-106 and other layouts but I would love to see pictures of different store layouts at Christmas time.
I know it sounds like the needle in the hay stack.
