There are some clever mechanisms employed to ensure the layout can fold flat against a wall, including two spots where sections of the track actually disconnect and fold while still working just fine when the railroad is up and running. The whole thing is run off of 12 AA batteries which not only powers the tiny locomotive pulling two passenger cars, but LED lighting effects around the layout, as well as sound effects that are triggered as the tiny train rolls through the tunnel.
If you’re having a hard time convincing family or roommates that a model railroad is an essential upgrade for your home, this is probably the better way to go with a surprise reveal of the final track layout. Remember, it’s always easier to ask forgiveness than permission.
