Bordeaux–Sète railway
The railway from Bordeaux to Sète is an important French 476-kilometre long railway line, that connects the southwestern port city Bordeaux (on the Bay of Biscay) to the southern port Sète (on the Mediterranean) via Toulouse and Narbonne. The railway was opened in several stages between 1855 and 1858. Route
The Bordeaux–Sète railway leaves the Bordeaux-Saint-Jean station in southeastern direction, following the river Garonne upstream on its left bank. It crosses the Garonne at Langon, and continues upstream along the right Garonne bank in eastern direction, turning southeast near La Réole. It crosses the river Lot near Aiguillon, and passes through Agen. At Castelsarrasin the railway leaves the Garonne and runs east towards Montauban on the river Tarn, where it turns sharply southeast, and then south to Toulouse. At Toulouse the railway leaves the Garonne again, following the small river Hers-Mort in southeastern direction. Beyond Carcassonne it follows the river Aude downstream, in eastern direction. At Narbonne the railway turns northeast until Béziers, where it turns east. At Agde it reaches the Mediterranean Sea coast, and runs northeast along the spit that separates the Étang de Thau from the sea. It reaches its eastern terminus Sète after 476 km. Main stations
