When devising this riddle, I had planned to have:-
"Clue 5: Two other National Rail stations include this station's name, but neither of these is close by - both are in different counties."
With the answer being Lostock.
In fact Langley Mill also meets the criteria of all five clues (and there are four "Langleys" on NR).
So I'll declare Langley Mill a correct answer and Marton has the Floor.
