The ballasted track system with prestressed concrete sleeper is the most widely used track system in the world today. The ratio between economy and reliability is unbeatable. Due to the high quantities produced, the design of these sleepers needs to be optimized in order to take maximum advantage of the economic benefits of the ballast/concrete sleeper system. RAILONE is therefore very familiar with the current standards for the design and manufacture of prestressed concrete sleepers from Europe (EN), North America (AREMA), Asia (diverse), or Australia (AS), among others, and can offer its customers a noticeable advantage here.
