If I had the space, money and time I would recreate the 1949 layout but use Atlas O track because Lionel did not have the vision to remake Super O track in a variety of radii.
Even as a child I never appreciated the Super O showroom layout. It appeared to be to futuristic for me' But I love Super O track. I only use Atlas because Lionel did not remake Super O. IMHO Atlas O only exist because Lionel did not remake Super O. I ran trains on Super O from 1970 until 1985 when the O72 switches became available and I switched to O gauge. I never had a roller problem.
I appreciate Brian Miller and his wife sharing their accomplishment with us.
