The Tegernsee-Bahn Betriebsgesellschaft is a member of the Fare Association of Federal and Private Railways in Germany (Tarifverband der Bundeseigenen und Nichtbundeseigenen Eisenbahnen in Deutschland or TBNE).

The firm was reorganised into a property and holding company, and was renamed in 1999 to TAG Tegernsee Immobilien und Beteiligungs-AG.

In June 2001, 44% of the public Bau-Verein zu Hamburg AG was bought; through a swap action and further purchase its share rose in early 2002 to 88%, but fell again afterwards to today's 69%.

In November 2002, the Real Immobilien GmbH was founded, together with a subsidiary, Sachsen LB, into which properties in need of repair were bundled.
