Former 4042.02 as StLB ET 12 in Peggau-Deutschfeistritz (1992)

The series BBÖ ET 11 was an electrically powered railcar of the BBÖ .

Despite the economic crisis of the 1930s, there was still enough wealthy public who wanted to travel to Salzburg , the Gastein Valley and the winter sports resorts of Zell am See and Innsbruck . In order to create suitable quick connections, the BBÖ ordered two electrically powered railcars, the structural part of which corresponded to that of the VT 42 diesel railcar . Both railcars were delivered in 1936. The trial run on the Tauernbahn Salzburg – Spittal and from Zell am See to Badgastein went well. The vehicles were also very well received by the passengers.

In 1938 the Deutsche Reichsbahn classified the vehicles as the ET 42. After the Second World War , the ÖBB referred to it as 4042.01-02 . They were now used on the Attnang-Puchheim- Salzburg route. As electrification progressed, they finally served fast connections between Linz and Salzburg and Vienna and Salzburg. During this time, the failure-prone control was modified.

Since their low performance did not allow them to be used with additional cars, new, more powerful railcars took over the city express traffic. The 4042s were now used in Salzburg regional traffic. In 1966 they were sold to the Steiermärkische Landesbahnen (StLB), which they used on the Peggau – Übelbach route - painted in their corporate colors of yellow / red at the time and designated as ET 11 and ET 12 .

Since they were taken out of service in 1996, the vehicles have been owned by the Nostalgiebahnen in Kärnten (NBiK) association, which refurbished them to be operational. In October 2014, the first test drives with the 4042.01 were completed. The railcar was again given a color scheme in ivory / blue. On April 28, 2016, it received its new network approval and is used for special trips.
