 It was forecast that the tramway would carry 50 million passengers a year and, based on research of Croydon Tramlink, promoters anticipated around 19% of those passengers would switch from using a car to the tram for their journey.The scheme was budgeted at a cost of approximately £200 million, and the line would come into service by 2009.The tram was designed to run along the congested Uxbridge Road from Uxbridge to Shepherd's Bush and replace the heavily used 207, 427 and 607 bus routes.
