The TCDD Open Air Steam Locomotive Museum (Turkish: TCDD Açık Hava Buharlı Lokomotif Müzesi) is a railroad museum in Ankara, Turkey, which focuses on the history of steam locomotives that operated on the Turkish State Railways. The museum was originally located in a park adjacent to Ankara Central Station, and when the property was needed for the station's enlargement project in 2014, the museum was moved to the current location near Wonderland Eurasia. The museum is owned and operated by the Turkish State Railways (TCDD), who also manages the Ankara Railway History Museum, as well as Atatürk's Car and Railway Art Museum.[1]
