Jelaskan Ghana dari Lebar sepur ganda

Ghana is converting its narrow gauge to standard gauge, and is installing dual-gauge sleepers as an intermediate stage.

In Greece, the line between Athens and Elefsis (now closed) was dual gauge in order to allow the  gauge trains of the Peloponnese rail network to pass. It also allowed standard gauge trains to reach the Elefsis shipyards. In Volos, a short section of track between the main station and the harbour used an unusual triple gauge, to accommodate standard gauge trains from Larissa, metre gauge trains from Kalambaka, and the  gauge trains of the Pelion railway.
