  1. Map shows westward extensions from Samsun Gar to Çarşamba and the industrial park. Will these be reopened or should they be deleted from the map?

    • Thanks for quick reply – you are right that the tramway from Samsun Gar through the industrial park to Tekkeköy is running now and is being extended to the airport. But as far as I know the train line to Çarşamba has been disused for some time.

  2. Yes, but not due to Samsun-Kalin project.

    By “open”, I mean there exists a line and no engineering works on that line.

    There is most probably no traffic because it would be inefficient to run locos on that closed network with that little traffic.
