The Class D62 (D62形?) is a type of 2-8-4 wheel arrangement steam locomotive built by the Japanese National Railways (JNR) in 1950 and 1951.
20 Class D62s were rebuilt from the earlier Class D52, which had a 2-8-2 wheel arrangement. Following the launch of the Class D62, other 2-8-2 locomotives (Class D50 and Class D51) were also converted to 2-8-4, becoming Class D60 and Class D61, respectively.
No examples of the class have been preserved.
The D62 is the model upon which the Transformers character Astrotrain is based.
