Hello Onur have just found your terrific website. I live in Melbourne, love trains and travel to work on electric Metro and then DMU. Like many Australians I have been to Turkey (three times in my case), but have never travelled on Turkish trains – other than from Sirkeci out to the end of the line on the Metro – plus had a look at wonderful, wonderful Haydarpasa station on last visit (2012). Hoping to get back to your beautiful country next year – your information on train travel within Turkey is really excellent. Best wishes.
