Dudullu is an underground station on the M5 and M8 lines of the Istanbul Metro in Ümraniye.[1][2] The station is located on Alemdağ Street in the Yukarı Dudullu neighborhood of Ümraniye. Connection to IETT city buses is available at street level.
Both M5 and M8 lines operate as fully automatic unattended train operation (UTO). Both stations consist of an island platform with two tracks. Since the M5 and M8 are ATO lines, protective gates on each side of the platform open only when a train is in the station on M5, and full height doors are used for M8.
The platform of the M8 line is under the platform of the M5 line.
The M5 portion of the station was opened on 21 October 2018,[3] with the M8 portion opening on 6 January 2023.[4]
