If you search for Old Scottish Maps you should turn up a site which has all the UK and all the OS maps going back to when James Spooner worked for the OS. The OS started because we had no accurate maps for the military in case Napoleon invaded.
With regards to the location of the station, wasn't that for the convenience of George Newne? IIRC the cliff railway was to persuade the great unwashed to go down into the town out of his sight!
