Currently, I have "too much" rolling stock and Engines.
It will not all fit on the layout, not even close.
I have 2 complete consists in the shipping cartons.
(They have both been run but went back in boxes due to lack of storage on the layout)
There are 5 engines on the tracks and there is one more on order. Each has a powered siding to sit on with a consist (except the one on order, need another siding there).
I have 2 docksiders and 2 Galloping goose units on the plywood with the Phantom.
I didn't count the older conventional engines, at least a couple in set boxes.
Those are used for temporary kids layouts at family gatherings.
SO
I'm expanding the layout from 6.5' X 23.5' to 11' X 23.5' around the walls.
It will have a 3' X 8' hidden yard underneath for extra on rail storage.
This has the wonderful benefit of eliminating 2 crawl-under points to fix problems on the back half. The stairs will now end inside the layout.
A Drop section is needed to access the back part of the basement, but this is not a big problem, in the summer It has walk in access from outside and in the winter it's too cold to use. I just need to be able to get the Christmas decorations thru twice a year, once each way.
