This past week I started building a poplar bookcase which will eventually be crowned with a shelf layout in N-gauge. The layout will be loosely modeled after Hemyock Station on the Culm Valley Light Railway.
The bookcase is roughly 60″ long and 54″ tall, with 11.25″ deep shelves and a 14″ wide top. It will replace two existent bookcases along a wall in the study. The layout proper will be 66″ long and 16″ wide. Eventually, I will build modular additions which will be stored away when not in use, and the layout will be removable for expanded operation.
