Various studies, from 1989 onwards, considered the reintroduction of trams to Edinburgh. In 2001, a proposal for a new Edinburgh Trams network envisaged three routes across the city, Lines 1, 2 and 3. Line 1 was a circular route running around the northern suburbs, with the other two forming radial lines running out to Newbridge in the west and to Newcraighall in the south respectively. All lines would run through the city centre.
