From Skopje to the sea by train

The "Balkan Travellers" website reports that two summer-only train services Skopje to the seaside beging operating this week. A daily overnight service from Skopje to Bar on Montenegro's Adriatic coast will run until 31 August, while a train to Varna on Bulgaria's Black Sea will run on Saturdays only until 4 September. For those of you puzzling over rail maps of Southeast Europe: both trains travel via Niš in Serbia.
