Metro lines, particularly in older existing tunnels, often have to be constructed within confined cross-sections. This requires low-profile sleepers for both track and turnout applications.

For precisely these applications, RAILONE has developed a sleeper with a particularly low-profile design similar to a timber sleeper, while meeting all other requirements of tram and metro systems.

It can also be adapted and equipped to accommodate existing components such as conductor rail supports, check rails or derailment protection devices.
