The Lokomotiv-Versuchsamt Grunewald or LVA ('Grunewald Locomotive Research Office') was a facility established from 1920 to 1945 at Berlin-Grunewald in Germany that conducted trials on railway vehicles.
After the Deutsche Reichsbahn-Gesellschaft was founded in 1925 the Railway Central Office (Eisenbahn-Zentralamt or EZA) that had existed since 1906 was renamed to the Reichsbahn Central Office (Reichsbahnzentralamt or RZA).
Amongst other things, they carried out numerous trials on steam locomotives and created the scientific basis for the performance measurement of railway vehicles.
In 1945 the work at Grunewald ended, due to the war, and was continued in East Germany at RAW[1] Dessau as well as in Halle, and in West Germany initially at Göttingen, and later in Minden and München.
The following employees are particularly closely associated with the establishment: At the site today are a few Deutsche Bahn office buildings, several small firms and a golf course.
