A question to any member - I have heard some say that using crumpled aluminum foil as a tunnel liner works. Does that interfere with any TMCC signal and/or operations? What are some other suggestions? I've spent a day making some liners from plastercloth. They look great from the inside but they are proving difficult to fit in the allotted space. I am just looking for an alternative that is easier to work with.
I know that this has been discussed before but I couldn't find the thread.
Thanks,
Dennis
