Kocamustafapaşa station is a railway station on the Sirkeci-Kazlıçeşme Line.[2] The station is located in the Samatya neighborhood of Istanbul's Fatih district. Kocamustafapaşa was closed in 2013 due to the closure of the whole B1 line,[3] after the opening of the new Marmaray line. The station was renovated and reopened as part of the T6 line that was inaugurated in February 2024.[4]
