When I was living in Texas I would set up a carpet railroad in the house a few times a year due to not planning to live in Texas not over 5 years til retirement. One day I had a derailment on the railroad. When I took up the track the wife noticed that I got her WHITE CARPET dirty with oil from the engine.
SHE WAS VERY, VERY, VERY MAD at me. I had to clean the carpet and did not set up anymore carpet railroads for a year. When we moved to Arkansas she said that my trains where ban for her house and NEW CARPET.
SO she made me build this so to keep her carpets clean:
SO PLEASE do not get the wife's carpet dirty you may end up like me.
P.S. I showed her, I build my new carpet central railroad 4 foot off of the floor and installed brown carpet in the room.
