Sanding Systems

While conditions leading to poor adhesion have been well investigated, methods for addressing the problems have not. The main adhesion enhancer used on railway networks world wide is sand. Sanding is … Continue reading

Rail-wheel Lubrication

Rail and wheel wear can be reduced dramatically by proper lubrication. In addition, lubrication can help in saving energy and reducing noise. Rail-wheel lubrications applies by automaticly or manually. Advantages of automatic lubrication; Maintenance … Continue reading

Buckled Rail

On warm days, rails in direct sunshine can be as much as 20 degrees centigrade above air temperature. As rails are made out of steel, they expand as they heat … Continue reading

Guard Rail

Guardrails (also known as guard/ girder/ restraining/ check rails) are used in transit systems to reduce rail wear in sharp curves and to increase the track’s resistance to flange climb … Continue reading
