Trepol Bay is a smallish, N Scale, layout with a viewing area of approximately 5ft by 2 feet and an extensive off scene fiddle yard.
It is set roughly in the period 1958-65.
The assumption is that the Southern Railway built an extension from Wadebridge to the fictitious North Cornish port of Trepol Bay (located approximately where Watergate Bay is).
I assumed that the Great Western also reached Trepol Bay from the Newquay to Par line making it possible for trains to reach Penzance from Wadebridge.
We have a rail served harbour with the main line with its somewhat grand station set above it.
