The GM 8 is a tram - railcars of Gmunden tramway .
prehistory
In 1957 and 1958, Duewag delivered twelve four-axle open- plan cars (Tw 241 to 252) in one- sided design to the Kiel Tram , which they had commissioned in 1956. In contrast to the open-plan cars produced up to then, they were given the head shape of the articulated railcars presented in 1956 with a rearwardly inclined front plate. Corresponding vehicles were only built in ten copies for the Bonn tram in Germany .
Potential exports to Austria stood in the way of the country's strong import restrictions. Six railcars of this design for the Innsbruck tram (numbers 61 to 66) were therefore built in 1960 under license from the Lohner-Werke in Vienna, which in 1967 delivered another to the Vienna tram (number 160).
The last newly procured vehicle for the Gmunden tram came from 1912 in 1961.
History and description
In 1961, Lohner built a large-capacity multiple unit based on the model for the vehicles delivered to Innsbruck for the 2.5-kilometer tram route from the city center to the train station . However, it differed from them in several ways.
The car called GM 8 was, unlike its predecessors, designed as a bidirectional vehicle. It is the only two-way open-plan car with Duewag fronts with sloping windows. However, since all Gmunden tram stops are on one side, it only has doors on this side. These are designed as three individual doors, which also makes it unique.
Due to the steep gradient of the route of up to 9.6 percent, the GM 8 was equipped with two 100 kilowatt electric motors that are fed with a direct voltage of 600 volts. Five different braking systems ensure sufficient safety even on steep slopes.
The car initially had 34 seats and 32 standing places. The passengers were handled by a shuttle conductor , a passenger flow was not provided. In the 1980s, the GM 8 was converted to one-man operation, which increased the number of seats by three.
Museum vehicle
During a general inspection in 1994, care was taken to preserve the original style elements. The vehicle is still presented in the white and red paintwork with the tip drawn down on the fronts and chrome trim strips. After being replaced by new vehicles in summer 2018, it was retained as an operational historical vehicle.
