The Mangfall Valley Railway was part of the first rail link between Munich and Rosenheim (and beyond that to Salzburg/Kufstein), the so-called Maximiliansbahn.

Not until 13 November 1858 was the first "real" station opened in Rosenheim complete with locomotive shed and turntable.

The railway was mainly used at that time to transport coal from the mine at Hausham to the Salinensudhaus salt works in Rosenheim.

Several new stations, at Feldolling, Hinrichssegen, Bad Aibling and Rosenheim, were to have been built some years ago; planning for them began in 1995.

However, by the end of 2019 the stations Feldolling, Hinrichssegen, Bad Aibling Kurpark and Rosenheim Aicherpark had been opened.

Contributory cause was the interruption of telephone and communication lines between Bad Aibling and Kolbermoor at the end of World War II.
