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.[1] 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.

Preservation[edit]

No examples of the class have been preserved.[2]

In popular culture[edit]

The D62 is the model upon which the Transformers character Astrotrain is based.[3]
