My vote goes for Edinburgh Park, between Edinburgh and Glasgow, which always seems to be a 'Marie Celeste' of a station.
I don't know if you're aware but the station signs were put in at an angle (a very slight one tbf so not really discernible by the human eye) to ensure that they squeak & squawk in the wind just like the ghostly abandoned rigging of a phantom ship.
