The Croydon Tram – inspired by Warhol
The Croydon Environment Audit 1995 estimated that nearly 880,000 tonnes of CO2 are emitted by vehicles in the Croydon area every year. Powered by electricity wires overhead, these trams do not emit fumes or pollutants and are a major step forward in reducing overall emissions across the city. Furthermore, they generate none of the engine noise of traditional vehicles, and are far more agile than buses fitting around existing buildings and infrastructure.
