Otogar is a rapid transit station on the M1 line of the Istanbul Metro. It is located in southwestern Bayrampaşa in the center of the Esenler Bus Terminal. Otogar was opened on 31 January 1994 as part of the M1's extension to Zeytinburnu. The station has three tracks with two island platforms and is only one of four stations in the metro system to have such a layout, the other being Yenikapı, Bostancı and Sanayi. West of Otogar the M1 splits into M1A and M1B service.
