Städtische Straßenbahnen Wien tram type H1 no. 2260
(Simmering 1910). Length 10.5 m, wheelbase 3.6 m, weight 13.2 t,
power 76 kW. During the second world war, as an anti air-raid
blackout measure, trams and other vehicles had to be darkened
during the night, so that they would not appear as targets for
aerial bombings. The headlights were covered up with only a
small opening remaining and the windows were obscured in
transparent blue, the interior lights were significantly reduced.
