Aleppo was one of the major stations of Syria that has been connected with the Baghdad Railway in 1912, within the Ottoman Empire. The connections to Turkey and onwards to Ankara still exist today, with a twice weekly train from Damascus. It is perhaps for this historical reason that Aleppo is the headquarters of Syria national railway network, Chemins de Fer Syriens. As the railway is relatively slow, much of the passenger traffic to the port of Latakia had moved to road-based air-conditioned coaches. But this has reversed in recent years with the 2005 introduction of South Korean built DMUs providing a regular bi-hourly express service to both Latakia and Damascus, which miss intermediate stations.
