"Regarding the changing positioning of lifts close to Engineering, the concept of multiple roughly similar engine rooms rears its multiple roughly similar heads again..."
Sorry for the confusion. I just wanted to provide a sense of orientation in the real life studio sets, not the in-universe location of "engine control room" (Season One) versus "engineering section" (Season Two).
But again, is there any
dialogue in TOS where the location of sickbay is explicitly stated to be on deck 7? (According to The Making of Star Trek
and the producers' intentions it was deck 7, FJ adopted the concept etc. and this is why we all believe sickbay to be on deck 7).
