Hint for ESR station codes validator. ESR (Единая сетевая разметка, Uniform railway marking) code is an unique station code used in USSR and later in former USSR countries.


  • Use 6-digits ESR station code to resolve ambiguous station name matching inside one region.
  • Use 0 as value to mark station without ESR code.

Don't use this tag to add ESR code to OSM database. It's only hint to help validator to resolve some rare cases.
