I would not think so, and what little could be put in there would be ineffective, I am sure. Plus - per the visible heat sink on the TMCC version anyway - foam near the motor would tend to hold the heat in, not a good thing.
I have learned to embrace the sound; Pullmor-equipped Lionel equipment always had more in common with household appliances than model railroading anyway. Part of the "charm" and durability.
