In this form it was about 840 yards (760 metres) long, and ran from a station at the Queen's Gate, parallel to the Eastern and Northern Carriage Drives, to a station at Chelsea Bridge, via a "halt" at the Funfair. It continued with other Barlow locomotives until 1975, when the line closed, partially due to the decline of the funfair itself.
The railway in its present configuration spanned a distance of about 840 yards (760 metres), extending from a station at Queen's Gate and running parallel to the Eastern and Northern Carriage Drives to one at Chelsea Bridge, with a brief halt at the Funfair. It continued to operate alongside other Barlow locomotives until it was closed in 1975, largely due to the funfair's declining fortunes.
