Need glue suggestions for "carpet" grass.

I don't think I had the exact type of carpet, but I did use a green indoor/outdoor type of product that was similar many years ago.  (Used to come in 6 foot by 10 foot rolls if you didn't want to buy off the huge roll at the home center, I think it still does).

I used a staple gun, probably with something like 5/16" ARROW staples to hold it down along the edges.  In my case, the staples didn't show much (though I will admit occasionally it took a few tries or shifting location a little - staples do not do well if you are over a knot ).  The pile on yours might be  a little lower, so maybe they would show more.  But it's a thought, and no chemicals involved.  Once firmly attached, I don't imagine the staples would cause much of a dangerous situation for the cat, though obviously you would not want loose ones floating around that could easily be dislodged and ingested.

But then again, I used it under tubular track without cork roadbed (and the grass mat went down first).  Looking at your picture more closely, it seems the track is already down, so maybe stapling it would be too awkward.

We have installed a lot of this type of floor covering over the years.  The go to adhesive would be  Henry #356.  Use the proper trowel, do not place any concentrated weight on it over night.  Knees or elbows can put a dent in it until it is cured.

However I would be reluctant to glue this down on a train platform.  It IS a serious commitment!  You will not want to be the one to remove it.  I would seek another means of fastening.

Consider sealing the wood surface and use premium double face tape.

If you are local to I-95 @DE/PA state line I would give you a gallon of Roberts Latex flooring adhesive.

With time and warmth the carpet will lay flat.  As the wrinkles flatten the edges will expand.

Staples may give you a pinch dimple.   The only way we ever stapled it is under a stair nose where dimples are  not seen.

I would not glue it.  We have used carpet on two different layouts and all we did is to use short small headed nails. Does not require very many fasteners and it is easy to remove if needed. Have reused  some of the carpet and one would never know that it had been used once before.  Start by tacking down one edge then hand stretch and smooth with your hand and use a fastener as needed to keep  wrinkles out.

To assist the process once you have started you can use a few longer nails across the table or a ways down the table as temporary fasteners after pulling on the carpet leaving them up so you can pull them out as you work your way down the table.  You will be surprised how few nails it will take.  Small headed nails do not show on our indoor/outdoor carpet. Give it a try

The track is already laid

The track is already laid making that scenario a bit difficult. Was going to use another method but changed my mind.
