U.N.C.L.E.: I was really reluctant to archive this as it was one of my earliest caches and has been in place for almost 6 years. However, cumbyrocks log note alerted me to the fact that something may be going on at the site so I checked it today. Recently the floor of the tunnel has been lowered to allow bigger trains through and that stopped access to the cache for an extended period. That work is all finished but new work has sprung up above the tunnel portal. I have no idea what it is about and there was no-one on site today, although there is machinery present. As cumbyrocks noted, there is a new track cut in adjacent to the cache hiding place. Looking at the marks on the road there is obviously a lot of heavy machinery and trucks moving about here. So purely for safety reasons, and the fact that I'm unsure what is going to happen here in the near future, I have archived this cache and moved the container to a new location a bit further back down the road where things should be a bit safer.
