The trains arriving from Sarajevo enter the map from the top and get in to the long, straight tunnel before Grad station. After it in a side valley the track starts its descent and crosses the valley in a viaduct, then turns back to the main valley, where the tracks run at three different levels. After some horseshoes over Ovčari village the track nearly reaches the Neretva river, but it's still 200 metres above the river, so it turns back in a sharp curve in a tunnel. After it the tracks arrive at Ovčari station.
