  1. Looks like a beaut of a bridge, not to mention a beaut of a high-speed line! If freight trains don’t use the bridge, will they use the tunnel under the Straits?

  2. Phil,
    The Marmaray project is many years behind schedule, and the specification has been changed several times. The lines which ran into central Istanbul on both Asian and European sides were both completely worn out, so the tracks have been lifted and all the signalling and power equipment removed, in anticipation of a total rebuild. The central section – including the tunnel under the Bosphorus – has been open for a few years. However there are still significant gaps on both sides, where total rebuilding of the railway hasn’t even started yet. All that is left is a muddy path where the railway used to be. You can expect to wait for another couple of years before through trains start running, I would guess.

    1. Thanks, Jeff, for your detailed response. That Europe and Asia may some day be able to interchange freight traffic is exciting. Let’s hope that some day comes soon!

      I also look forward to Europe being linked to China and the intermediate countries via a standard-gauge line. Such interchangeability has been a given in North America for over 100 years, as it has been in all of Europe, except Spain, I think.

      By the way, may I ask you a favor? I’m a professional writer/editor with 16 years’ experience, most recently as editor of Investor’s Digest of Canada based in Toronto.

      But I’m now hoping to start writing — for pay, of course!– about railways and airports. So, do you know of any railways, railway industry organizations, or construction companies that build railways that might be looking for an English language writer/editor? With such companies, I’m confident I could add value.

      Thanks

  3. I have got one question: As of now I thought when Marmaray is complete, the YHT and hopefully some mainline trains are going to start from / terminate at Haydarpaşa.
    Now this article suggests that a few years after the completion of Marmaray, YHT trains to Ankara and Konya are going to cross the bridge, which is incompatible to connecting Haydarpaşa. Does that mean, Haydarpaşa is going to revived just for a few years and then closed down again (at least for YHT), having the trains terminate at Halkalı?

    1. Good question. I just can say what I guess. Some of the trains will depart from Halkali, and some others from Haydarpasa. I’m quite sure there’ll be enough passengers from both sides. And note that Haydarpasa is a much better point for accessing city center of Istanbul.
