Mike Thanks,
No it is not yet taking up the entire basement, only 2/3s.
But where the temporary work bench for the power saws/drills and shelves packed with stored scenery are located in the northeast corner, will one day be removed and become an off scenery helix/staging/reverse loop to lose a train for a few minutes. That is a 10' x 15' area to conquer.
Hence the pre-installed 0-72 switch and to be relocated lower tunnel portal for the future lose a train somewhere and hope it comes back sometime track.
