A719 nine miles south of Ayr
Ayrshire

Known locally as "Croy Brae" This runs the quarter mile form the bend overlooking Croy Railway Viaduct in the West (286 feet above ordinance datum) to the wooded Craigencroy Glen (303 feet A.O.D.) to the East. Whilst there is a slope of 1 in 86 upwards from the bend top the glen, the configuration of the land on either side of the road provides an optical illusion making it look as if the slope is going the other way.

Therefore, a stationery car on the road with the brakes off will appear to move slowly uphill. The term "electric" dates from a time when it was incorrectly thought to be a phenomenon caused by electric or magnetic attraction within the brae.
