This is the entire P&W layout prior to the 2006 expansion project.
Only one train could run effectively on this layout. How could we have 
two trains running at the same time without tearing up the entire layout 
and starting from scratch?  After many ideas were discarded, Phyl and I 
finally settled on an independent inner track that would tie in with the 
existing layout.  We decided to construct an "island" in the middle space with a 
removable insert to allow access to the entire layout, old and new sections. 
The island would also contain new freight yards. The old freight yards on near right
portion of the picture would be removed to make space for another town.
