Blackpool runs a mix of double-deck and single-deck cars, though there are more single-deck trams in the fleet. The double-deck trams are used the most in the tourist season. The single-deck trams are not used as much at that time. They are sometimes used though when it is busy to let the system carry more passengers. Blackpool was the only town in the UK that kept its trams. Between 1962 and 1992 Blackpool was the only town with a tramway in the UK that was not a preserved system. The last English city to lose its trams was Sheffield in 1960. The last in the UK was Glasgow in 1962. Trams have been returning to the towns and cities in Britain since the Manchester Metrolink opened in Manchester in 1992.
