I should mention that when considering whether or not to digitally control turnouts one need not go 100%. Based on operational need/utility some turnouts on my railroad are digitized, some are controlled by traditional panel mounted selectors, and a few are hand throws. All turnouts in the maze of crossovers approaching the staging yards are digital so that the tower operator (no CTC on PRR's 1950's main lines) can select the rout in and out of staging with one touch of a button.
I also use digitally controlled turnouts in areas where the turnout can be thrown from multiple panels. Bi-color (red-green) LEDS wired in series with the switch motors indicate the status of the turnouts. Though the digitized turnouts can be thrown using the walk around cabs, we generally don't use that capability as it is too easy for operators to select the wrong turnout number.
