The line’s importance for freight also partly arises from its access to the Munich North marshalling yard (Rangierbahnhof München Nord).

Near the marshalling yard's exit tracks there is a connecting curve to Moosach on the line to Laim.

To the east of the marshalling yard, the line runs along the northern edge of the Olympic Village.

Passenger services ran to the former München Olympiastadion station, which is located on the line here, during the 1972 Summer Olympics.

At the same time, another local railway for freight traffic was opened from Johanneskirchen, a station on this line, to München-Schwabing.

The direct connection of the North Ring to the Mühldorf line was completed from Johanneskirchen to Feldkirchen in 1941.

Today part of it is still used for the research and technology centre of Deutsche Bahn and still houses experimental vehicles.
