Good question!
Mine is in our basement. My wife & I and our two young sons live in a small bungalow in an old Toronto suberb.
Right now, a friend uses our basement 3-4 days during the week, so I have to stow away my small 4x6' layout after use on weekends. I obviously also have to carefully wrap up and put away all of my locos and rolling stock. The advantage of this, is that it keeps everything clean! :mrgreen: and it only takes me 20 to 30 minutes to set everything up.
At any rate, this autumn our friend will no longer need to use our basement -- so I'm planning to turn the basement bedroom into a train/layout room! :mrgreen:
:mrgreen:
This will also move the layout away from our kids' play area -- overall, they're pretty responsible with our trains, but I get very nervous when they have friends over!
(They actually broke an axel on one of my nice brand new British locos but I was able to get it repaired.)
So that's my long-winded answer!
