In two days I will arrive in Turkey in Kesan by bike. From there I will travel to Istanbul. If possible I would like to enter the city by train. I had some difficulties to find the information needed in english. These are my questions: From where can I take a train to Istanbul? Tekirdag? Muratli? Corlu? What is the timetable for that train and where can I get the ticket? Is it possible to transport a bike in that train?
From Muratli and Corlu you can take the train, and from Tekirdag you cannot. Check where train calls at below link. Tickets are available at stations. A foldable bicycle is accepted at all trains. For others, train must have a luggage car. Just show your bicycle to the clerk at station, and see if any train from that station can take the bike.
Sorry for not answering your question on time. Hope you had experienced well.
