The main signal "F5" at the fifth track, photographed at the exit from the shunting station of Crnomerec, in the direction of Zagreb Zapadni kolodvor (West Railway Station). This signal is one of those that literally never change. The regular traffic is in progress on the tracks 1 and 2, while the other tracks are mainly used for shunting, which is done in spite of the red lights. Photo: Toma Bacic Scan: Tin Sipos
