By using an innovative design and advanced production technique, Lankhorst has succeeded in developing a plastic sleeper that is totally optimized for use in the main track. The sleeper designed to maximize the lateral and longitudinal resistance in the ballast whilst using 30% less plastic than is used in the solid switch sleeper. This results in a lower cost price, lower transportation costs and an even lower carbon footprint. The plastic sleeper is thoroughly tested by the laboratory of the French national railway company SNCF. The French railways have installed a 1 km test track to evaluate their in track performance.

The plastic sleeper is available in the dimensions 275 x 150 x 2400 mm. The sleeper can be supplied with either flat or inclined baseplate areas.
