@Bill Park great scenery work and creative track plan!
Following on the passenger car sets discussions - "do they count as 1 or 5" - regardless, they do take a lot of room on shelves. As I intended to create an engine area in a corner of my layout, I decided I could add pull out shelves to hold "excess" passenger coaches. Each shelve holds 12 cars so this takes care of 36 cars leaving limited shelf space for displaying my intermodals and coal hoppers.
Still have to figure out the engine area track plan and associated details. I realized I only have 3 coal steamers, the rest are oil. Kind of minimizes the need for the coaling station. Have a water tower and fuel/water columns, although the latter make no sense with steam. A broad year range for the transition period is the only answer - roughly 1945 thru 2000. This is also calling out for an engine house - the base is 20 x 42 - any suggestions???
The black buttons on the table edge are touch toggles which provide switching to my new water front area. A ToDo is drafting a layout plan so the toggles can be mounted behind the plan. As is I cannot remember which toggle controls which switch, I need to see the plan to know which turnout I am changing.
