Train set "Oberammergau" of the German Federal Railways. It consists of the electric locomotive 169 005, a covered goods wagon, type Gs, a 4-axle flat wagon, type Rs, an open goods wagon, type E, and a hopper wagon, type F-z 120. On January 24, 1905, electric operations began on the 23.7 km long track to Ammertal. It was the first journey of an electric train under a simple alternating current overhead line. Thus, it became the first route equipped with a new system, known as "railway current," which is still used today in Central and Northern Europe. The line was initially operated with electric multiple units and later with small electric locomotives capable of speeds up to 50 kilometers per hour. The energy, in the form of single-phase alternating current, came from the Kammerl hydroelectric power plant on the Ammer River. Starting in 1930, the robust LAG 5 – later 169 005 – supplemented the electric locomotive fleet on the Oberammergau Railway. Despite its length of only 8.7 m, this small powerhouse proved to be exceptionally reliable. For decades, the railway, with its coziness and idyllic surroundings of a Bavarian local line, held a special charm for all railway enthusiasts. The era of the "Neinasechzga" in local transport on the Oberammergau Railway came to an end in May 1981. With the withdrawal of the old locomotives, regular operations began, and the charm of an incomparable era was irretrievably lost.
