Hi Spitfire, long time no talk. Looking at your layout, if you wanted to increase its size to empire you could use the peninsula as a Nolix area, look at John Armstrong's plan for the Athabasca railroad, back in MR some time ago, can't remember. A peninsula was used to raise the trains but it was a visible helix in a peninsula shape. Its hard for me to see how do able according to your diagram as there are no foot marks.
IF you put a view break down the middle of the peninsula, not only will it separate the views of the train climbing but make the rest of the layout appear larger.
Cheers,
Rick
