The ornate Ottoman-era terminus of the Hejaz Railway, completed in 1913 in a heavy Damascene style — black-and-white striped stonework, a high-pitched red roof, intricate window screens. Until 1917 you could buy a ticket here that would take you all the way to Medina; by 2010 you could still take the local line south to Bosra and Daraa.
Today, with the southern line out of service and the building largely empty, the station has become a museum to its own past. Locomotive 71, a vintage German-built engine, sits on display outside. Worth a look for the architecture and the period photos, especially if you have any interest in the Arab Revolt.
