The code used for the station. In North America, this might be something like NYP for New York Penn Station or OSB for Old Saybrook Station if it's an Amtrak station. In Germany, the Ril 100 code would be something like KN for Neuss Hbf. Abbreviations used by companies other than the operator can be tagged using railway:ref:(company)=*.
