We have 32 multipurpose vehicles and 29 locomotive-hauled rail head treatment trains (RHTT) – our dedicated, purpose-built equipment – that deliver our autumn rail head treatment (RHT) programme. Both these types of train are equipped with a high-pressure pump delivering 1,500 Bar and, if required, can apply adhesion modifier to each running rail.
Adhesion modifier is a mixture of suspension gel (so it can be pumped), sand (to help train wheels grip the rail), and steel or iron shot that is pushed through contamination (compressed leaves and debris) on the rail head to help the track circuits work correctly.
