] (a Ukrainian website organizing steam tours) cited information comes from Anthony J. Heywood & Jan D.C. Button, Soviet Locomotive Types: The Union Legacy (1995). The latter says the data in the original entry refer to MAVAG-built locomotives delivered in 1950.(Other builders included Briansk, Cegielski (Bulgaria), CKD (Czechoslovakia), Kolomna, Lugansk, Malaxa (Romania), Resita (Romania), MAVAG (Hungary), and Skoda (Cz).
