The transportation facilities of the people of Kocaeli were restricted by closing the Adapazarı Train Stations. One of the currently closed train stations is Köseköy train station. It was put into service for a very short time. Even for this temporary period, the steel station was built and the train station was extended. But like the Derbent train station, this train station is also closed. It is expected to be put back into service as soon as possible. The people of Köseköy want to reach Istanbul and Adapazar easily. The student, officer and worker living in this district are waiting for the train station to be put into service in order to use the train regularly.
