The NMBS/SNCB Type 64 was a class of 4-6-0 steam locomotives built as Prussian P 8s for German railways, delivered as war reparations to Belgium at the end of World War I. 168 locomotives of this type were delivered to Belgium, working mostly on light passenger trains operated by the National Railway Company of Belgium (NMBS/SNCB). The final locomotives of this type were withdrawn in 1967, marking the end of steam service in the country.

The Prussian Class P 8 of the Prussian state railways was a 4-6-0 steam locomotive built from 1906 to 1923 by the Berliner Maschinenbau and twelve other German factories. The design was created by Robert Garbe. It was intended as a successor to the Prussian P 6, which was regarded as unsatisfactory.
