The railway is in my attic, but its plastered and carpeted and has proper stairs leading up to it - its a proper room not a rafter filled empty space.
In order to get the trains going all the way round, i had to carefuly hack two holes int he wall, and run a bridge type construction inside the wall.
I have also recently installed a helix which takes the trains up afew inches.


if you look on my youtube channel there are quite afew videos of the layout as it is at the moment, including some on-board camera shots.
