The Baureihe ET 91 was a series of electric multiple units built for the Deutsche Reichsbahn-Gesellschaft of Germany. The units colloquially known as Gläserner Zug (Glass Train) were equipped with large panorama windows, providing an excellent outside view to the passengers. The vehicles were used for recreational trips only, especially in southern Germany and Austria.
ET 91 02 was destroyed on March 9, 1943 in a bomb attack on the Munich shunting yard. ET 91 01 survived World War II without major damage and was taken over by the Deutsche Bundesbahn From 1968 on, it was listed as Baureihe 491 in the DB numbering scheme, being assigned the number 491 001-4.
On December 12, 1995 the remaining unit suffered extensive damage in a frontal crash at Garmisch-Partenkirchen and was subsequently taken out of service. The unit has been stationed at the Bahnpark Augsburg in Augsburg since May 2005.
The unit is currently being renovated, however due to economical reasons it will not be put into a usable state again, the power bogie having been destroyed in the 1995 accident.
