Hi Nick, definitely not my layout, merely a contributor to the group...
I think the last time I checked the dimensions of the layout it was big x still pretty big
To be honest, I couldn't tell you the accurate dimension, but i'm fairly sure that the station section itself without the new extension is around 30 ft long, though I'm sure that a couple of people on here would be able to confirm that..
Hopefully soon, when we have trains going off scene on the new extension, we'll be able to create a nicely polished video of a session which can be shown on here and also on the Perfect Miniatures stand at exhibitions..
JB.
