Mrs tac, who is FAR more clever that I am, has the answer to this conundrum, and to many other conundra. She subscribes to the opinion that the earth is actually expanding, which would neatly explain why your rail no longer fits where once it did. Proof of this theory can be obtained quite simply by taking note that everything we want to find from an historical viewpoint seems to be buried, rather than simply lying on the surface. Here in Huntingdon, the entrance to a medieval church is actually four feet below the present street level…and archeologists, examining three local building sites, have found not only Anglo-Saxon graves, but a Roman one as well. By digging. Even our little 7.25" gauge track is slowly being subsumed into the landscape, and we have to dig it out every year or two. Theory proven. QED. tac
That would explain the global warming theory as well…we’re closer to the sun.
