Suburban flights, which were interrupted due to YHT construction, have not yet begun. Istanbul-Adapazari line is still closed to the previous day.
Due to the construction of the High Speed Train Line, Adapazarı Express was lifted and the suburban flights between Istanbul-Kocaeli and Adapazarı were stopped. After YHT was built, suburban flights started again, but far from the old efficiency. Until recently, there was a mutual 4 trip between Istanbul and Adapazari. The train that did not enter the Adapazarı and Haydarpaşa stations, Tuzla, 41 Evler, Kuruçeşme stations did not stop and caused many passengers to suffer. Commuter trains increased the day before. The number of times 4 is increased to 5. However, many stops are still closed. TCDD officials hand in hand, the train line that serves thousands of passengers every day is requested to re-operate the old.Kocaeli Barış Newspaper)
