Some history about it:
In Emmering we can still find a concrete bridge that has never been in operation for a day. The street mentioned was supposed to cross the railway on it. However, the necessary embankment was no longer available and they were content with a track-like crossing of the lightly traveled stretch of road with the equally unimportant road.
Designed for two tracks, this section was also opened as a single track on October 2, 1939. In contrast to the other sections of the north ring, the later addition of the second track was dispensed with. The importance of the Olching Ost - Steinwerk section remained very low. Even during World War II, freight traffic on the Allgäu Railway was insignificant, and the northern marshalling yard to which it would have been directed did not yet exist.
This route only plays a macabre role in contemporary history. Precisely because of its limited use, the track at the stone works near Emmering could be used on April 25, 1945 for the erection of freight wagons, into which 3000 predominantly Jewish prisoners from the Dachau concentration camp or its Kaufering branch were loaded after terrible marches. Due to the rapid advance of the Americans, the victims could not be transported further to an imaginary Alpine fortress, for example. The survivors were freed in Seeshaupt.
