Marmaray project

The railway project connecting national rail network in Asian and European side through a rail tunnel under Bosphorus.

Marmaray is planned to be the backbone of public transport in Istanbul city. The suburban trains on Marmaray will run every 2 minutes in peak times and Marmaray will be connected to many existing, under construction and planned metro lines in two sides of Istanbul.

Not only suburban trains will run on Marmaray, but also high speed trains and conventional passenger trains will use it to access Haydarpasa, the main station in Asian side.

Marmaray will also be used by international and domestic freight trains crossing Bosphorus.

  1. Very much enjoyed perusing your blog about Turkish railways — a subject about which I know little, unfortunately! But from what you’ve written and from the little I’ve read over the past year or so, Turkey is now an exciting place to be for the railway buff! The tunnel under the Straits linking Europe and Asia is a wonderful development, given that it brings rail freight transportation between China and Europe on step closer!

  2. Once again, thanks for the update on these remarkable construction projects — projects that should shorten the distance between European and Asian railway networks!
