The TAG 7 is a superheated steam locomotive that was developed and built by Krauss-Maffei in 1936 with the serial number 15582 as EAG 7 for the private Eisenbahn-Aktiengesellschaft Schaftlach-Gmund-Tegernsee (EAG) - the later Tegernsee-Bahn AG (TAG). Today it is owned by the Bavarian Local Railway Association .
The tank locomotive with the 1'D1 'wheel arrangement, together with its sister machines LAG No. 87 and 88 , is the last and most powerful local railroad locomotive that was constructed in Bavaria. An output of 470 PSi (346 kW) allowed a top speed of 70 km / h in both directions. The EAG needed the new machine to relieve its two smaller machines EAG 5 and 6 (type Bayerische GtL 4/4 ) and to be able to gradually dismiss the now outdated machines EAG 3 and 4 from service. The TAG 7 proved itself so well that a year later two machines were replicated by the Lokalbahn Aktien-Gesellschaft (LAG).
TAG 7 served as the operating reserve of the Tegernsee-Bahn until 1975, at the same time the first museum trips on Tegernsee took place in the 1970s, organized by a working group of the German Society for Railway History (DGEG). When the expiry of the DAY 7 deadline threatened the end of the journeys and the scrapping of the machine, the Bavarian Local Railway Association was founded to raise the money for the necessary general inspection of DAY 7. The machine - de jure still owned by TAG - remained stationed at Tegernsee until the end of the 1990s, with the Localbahnverein financing all further examinations and maintenance. In 1999, after the transfer of operations on the Tegernsee Railway to the Bayerische Oberlandbahn , TAG finally sold the machine to the association. At the same time the depot in Tegernsee had to be cleared; TAG 7 has since been stationed at the Landshut depot. TAG 7 has had the PZB 90 train control system since May 2005 . The locomotive is shut down due to a boiler damage, and the association is planning to build a new boiler.
