A Royal Mail press release in April 2003 said that the railway would be closed and mothballed at the end of May that year. Royal Mail had earlier stated that using the railway was five times more expensive than using road transport for the same task. The Communication Workers Union (CWU) claimed the actual figure was closer to three times more expensive but argued that this was the result of a deliberate policy of running the railway down and using it at only one-third of its capacity. A local governmental report by the Greater London Authority was in support of continued use and criticized the increase of lorries on local roads, estimated to be 80 more trucks per week. The railway was closed on 31 May 2003.
