I did a quick survey of "The Cage" bridge.
From what I can tell, the starboard side stations forward of Communications (station directly behind Pike and next to turbolift which I labeled as Station 5) are never filmed as part of the bridge. With the exception of a BTS photo, Spock's library station (Station 4) console and instrumentation (with the printer) is shown only in close-up. His large view screens are also shown with Spock but not next to the other stations. In the BTS photo "ST 358", the view screen images do not match the close-ups with Spock.
Station 3 is never shown from what I can tell.
Station 2 is shown only from behind and only the lower console. The instrumentation and upper viewscreens are removed for the camera.
Station 1 is shown from the side and behind with the full stack and with the instrumentation and view screen removed. There are also BTS photos suggesting that Station 1 had targeting disks instead of the a traditional viewer.
It is evident that the full port and starboard rails for the lower section are not dependent on the presence of the different stations as you can see them in the BTS photo with Station 2 and 3 removed.
