So I got a new Zephyr DCC system, and picked up some decoders today. I installed one, and sodlered some feeder wire to a pair of rail joiners to attach to my test track. Said test track has foam roadbed glued to a piece of shelving with some Atlas code 83 track glued to that with yellow glue. Well, attaching the joiners to the end popped the end piece of track right off the roadbed.
Time to rebuild and use caulk, or just glue the track to the shelf and skip roadbed.

And to top it off the whole thing just got knocked off the arm of the couch and ALL the track popped off. I pulled and ALL of the roadbed came off too - the yellow glue did not adhere to ANYTHING. Tomorrow I will get some caulk and repair it and make it right. Just as I am finally set up to run a train, even if it is just back and forth over less than 3’…

Randy:
Though I used Elmer’s Carpenter Glue (the yellow) to re-inforce my wood joints and seal the 2" extruded foam base onto the frame, when it came to laying my foam roadbed, I instead used the Elmer’s all-purpose white glue (not the ‘school’ stuff), which seems to be a little more flexible. I think the yellow glue is better when there is a wood base to adhere to, and not foam to foam.
I’d definitely reccommend the more flexible Elmers White or caulk for foam to foam.

Both white and yellow glues are made for use on pourous surfaces (sez so on the label)–like wood, cloth, etc.
Foam is not real pourous, so I am not surprised those glues did not adhere under stress.
