The BBÖ ET 21 were electrically powered accumulator railcars of the Austrian Federal Railways . The ET 21 were the only accumulator railcars ever built and used in Austria .
As early as 1919, the BBÖ began developing accumulator railcars, which were then called storage railcars. The first railcar delivered by AEG in 1921 consisted of a motor car at the top and one at the end of the train, which were created by converting former Viennese steam light rail cars , as well as two converted light rail cars with the series designation Cut and a battery car in the middle, which was operated by of Akkumulatoren-Fabriks AG in Vienna . The vehicle, also known as the storage car, was essentially a low side car on which the batteries were housed, but which also allowed the staff to move from one part of the multiple unit to the other. The motor vehicles each had a driver's cab and together produced 140 kW.
The BBÖ had also tested accumulator railcars in which the batteries were housed under the passenger seats. However, this led to odor nuisance, especially when charging the batteries. In addition, the arrangement with a separate storage trolley made it possible to exchange a trolley with discharged batteries for one with charged batteries. The multiple unit could then be used again while the discharged batteries of the suspended storage car were recharged.
Since the test drives between St. Pölten and Traismauer were successfully completed, the BBÖ ordered three more multiple units, slightly modified compared to the prototype. The motor vehicles of the first were given the numbers ET 21.001–002 , the other ET 21.101–106 , although contrary to the regulations, the “ET” was not written on the vehicles. The storage wagons were given the numbers 1090.001 and 1090.101-103 (other documents speak of 1090.001, 101, 103 and 104 ).
The first two multiple units were used in the following two-day schedule:
Day 1: Salzburg - Straßwalchen - Salzburg - Hallein - Salzburg - Golling - Salzburg (150 km)
Day 2: Salzburg - Golling - Salzburg - Hallein - Salzburg (93 km)
The progressive development of internal combustion engine railcars meant that the storage railcars were retired in the mid-1930s.
