Leaf build up on the railhead can also cause signalling issues and 'disappearing trains' on the rail control systems (because of the electrically insulating effect of the leaves, which can prevent operation of track circuits).
British Rail conducted research, in 1976, to determine the suitability of Sandite for use as an adhesion improver.[5]
Sandite is usually applied by a special train which first clears fallen leaves from the rails using high-pressure water, then sprays the sandite onto the rail surface.[7] To assist the staff on the Sandite train in locating the sites concerned, in England and Wales black on yellow lineside markers were installed:[8]
The first sign, with three stripes gives advance warning of a Sandite application site
The second sign, with two stripes points where application should begin
The third sign, with one stripe points where application should end
From 1992, lineside marker boards were installed on the Scottish Region, based on alternative white octagonal boards to denote the commencement and finish points, with no warning sign.[9]
In The Netherlands, Sandite is applied by the first passenger trains of the day,[10] with special maintenance trains available too.
Belgian Infrabel operates a dedicated train, with a diesel engine at either end.[11]
