When the German provincial railroads were merged into the German Reich in 1920, the Free State of Bavaria, after lengthy negotiations, was granted a special status for the railroad system in its service area: the independent "Bavarian Group Administration". For example, the Bavarian signaling system was continued and there were no restrictions imposed on the acquisition of railroad locomotives and cars, especially for the requirements of the Free State. Also, the appearance, i.e. the paint and the lettering on the locomotives and cars, was a proof of the independence, since it generally differed from that used in the remaining territory of the Reich. The special privileges with respect to paint schemes and lettering ended around 1927, however, and other exceptions were successively eliminated by 1933, being eradicated by law in 1937 with the dissolution of the German State Railroad Company and the creation of the German State Railroad. As compensation for the loss of the special status, Bavaria was given the German State Railroad's central office in Munich, which was responsible for procurement of electric locomotives for all of Germany.
