In the 1930s, there was a need for faster and heavier express trains in Finland, and the Hv1–Hv3 classes were not powerful enough to fill the need. Lokomo Oy in Tampere built first two prototypes, and after successful trials 20 more were built. Most of the locomotives were fitted with Wagner-type smoke deflectors, but the last two, which were equipped with roller bearings, had Witte-type deflectors.

The class's nickname was "Ukko-Pekka", meaning approximately "(respected) Grandpa Pekka", after the President of Finland Pehr Evind Svinhufvud.

The Hr1 was built for coal firing, but during the coal shortage after the war in 1945, birch wood was used as fuel. Larger chimneys needed for extinguishing wood sparks were temporarily fitted.

The Hr1s were the most important express steam locomotive and could justifiably be called the "flagships" of VR until 1963, when diesel locomotives started to replace steam. Their use ended officially in 1971, but two Hr1s equipped with roller bearings were brought back to use for a short time in the spring of 1974. One engine, 1005, was a participant in the worst peacetime railroad accident in Finland, the Kuurila accident, in 1957. The engine is preserved at Haapamäki.

Hr1's sister locomotive was the Tr1 class, otherwise similar, but with 2-8-2 wheel arrangement and smaller diameter drivers for freight train use.
