[1] The line runs from Alsancak Terminal in İzmir to Bozanönü, where the Isparta branch begins.

The ORC opened the first section of the line, between Alsancak and Gaziemir and Seyiköy in 1858, thus becoming the first railway in Turkey.

Construction slowed during the following years due to financial problems, but the line was ultimately completed by 1866.

With a large ceremony the line was opened as the inaugural train ran from İzmir to Aydın on 1 July 1866.

New branches were built of the railway to reach important towns such as Isparta and Burdur and service increased over the years.
