Very nice layout plan
I presently have a 11.5x12 foot layout and I've found I have too many industries I'm trying to model. I would be happy to model just 1 industry completely than the 4-5 industries I have now that are at most partial representations of the real deal. I could possibly go to a 12x30 plan, but it would take up the entire upstairs space (I do have a plan already drawn, just in case ).
Seeing large layouts like this is just too cool. I saw Ed Rappe's PRR layout this past February and was overwhelmed at all the work he put into it.
