I have a problem that just occurred after about 7 or 8 years of operations. I have one 1 uno tunnel on my layout. in about 4 scale miles of double main line an probably the same distance in single. this tunnel is probably 18" to 20" long. For some reason the track has expanded and moved making a bow in both tracks. They are now almost touching. First question is why now, why there and what happened to the nails holding it in place? Second question is how do I fix it?
