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
Flash-butt Welding
The welding process is in principle a regulated electric short circuit with the two rail ends functioning as D.C. poles. The high current produces an arc between the rail ends, … Continue reading

Rail Profile
The weight of a rail per length is an important factor in determining rails strength and hence axleloads and speeds. Weights are measured in pounds per yard or kilograms per … Continue reading
Thermit Welding
When applied to the reduction of Iron oxides, the exothermic reaction generates sufficient energy to raise the reaction product temperature to in excess of 3,000°C at which both the metal … Continue reading
High-speed Rail
High-speed rail (HSR) is a type of passenger rail transport that operates significantly faster than the normal speed of rail traffic. Specific definitions by the European Union include 200 km/h … Continue reading
