H-Day

Håkan Trapp was a swedish photographer who documented the Stockholm tramway in the early 1960s before the ‘H-Day’ on 3 September, 1967 when Sweden switched from driving on the left-hand side of the road to the right. The ‘H’ stands for ‘Högertrafik’, the Swedish word for right traffic. Trams in central Stockholm, in Helsingborg and most lines in Malmö were withdrawn and replaced by more than one thousand new buses with doors on the right while some 8,000 older buses were retrofitted to provide doors on both sides.
